You are mistaken.
When you say, "
Nowhere is that said..." or "
Nowhere is that reflected..." what you mean is "
Nowhere is that reflected as my end-times view says it will happen."
In Matthew 23 and 24, Jesus stated the words "
this generation" twice (vvs. 23:36 and 24:34). The conjugation of the Greek is near demonstrative, which means the two words CANNOT be translated to mean "
that generation," or anything other than "
this generation to whom I am now speaking." Now we know the things Jesus said to "
this generation" in chapter 23 came true and they came true in the generation of the Pharisees to whom he was speaking at the time when he spoke those words. The temple was destroyed, and the Pharisees were wiped out. Those two events are facts of history. This places a burden on the person saying the "this generation of chapter 23 is different from the "
this generation" of chapter 24. There is no burden on those saying the two are identical because that would be the natural, normal, ordinary reading of the narrative. It is the difference that has to be justified and explained.
This is especially the case given the
fact the phrase "this generation" is used four times in Matthew's gospel (Mt. 11:16, 12:41, 23:36 and 24:34), and on all four occasion Jesus is talking about the generation to whom he is speaking at that moment. So the obligation to justify the protest is not on the reader who views all four mentions synonymously, but on the one who treats one verse differently than all the others. Furthermore, Luke records Jesus using the phrase eight times and all eight of those occasions is a reference to the people to whom Jesus was speaking at that time. The same is true of Mark's report.
Conclusion: There are 14 different occasions when Jesus is recorded as having used the phrase "
this generation" during his time on earth and they all mean the same thing.
That makes it incumbent upon the modern futurist to explain how one mention out of 14 is the one that is different from all the others AND s/he must do so
exegetically, not post hoc.
So protest that begin with questions are worthless, especially if and when the question is "
When did that X happen?" because whatever "X" might be it happened in "
this generation." It did not happen in that generation sometime in the far, far distant future to people Jesus and the twelve never met. Making "this generation" into "that generation" is adding to the text of scripture, and doing so eisegetically, not exegetically. Asking about conditions occurring after the canon of scripture was closed is a
post hoc argument (it's a logical fallacy) and it subjugates scripture to history, not the other way around. In other words, if scripture is authoritative, then scripture renders history, not the other way around. Both means of protest are inappropriate (but they are constantly used by end-times teachers). Now that you know them watch and listen for them and disregard anyone who uses them.
The way the prophecies should be read, interpreted if necessary, and understood is by first using other scripture. For example, in Matthew 24 and Luke 17 Jesus says at the time the events he's describing occur it will be like it was "in the days of Noah," and he describes how pairs of individuals will be working and one taken away and the other left behind. The modern futurist interprets that to mean the individuals taken away is a reference to the rapture. The pre-tribulationists further argue this is the rapture preceding the tribulation and God is sparing the Christians the suffering that will occur. The problem with those interpretations, however, is that in the days of Noah it was the ones who remained that continued to live on in a covenant relationship with God and
the ones who were taken away were destroyed! They were
not saved.
Luke 17:26-27
And just as it happened in the days of Noah, so it will be also in the days of the Son of Man: they were eating, they were drinking, they were marrying, they were being given in marriage, until the day that Noah entered the ark, and the flood came and destroyed them all.
Those taken away were destroyed.
Genesis 9:15
...I will remember My covenant, which is between Me and you and every living creature of all flesh; and never again shall the water become a flood to destroy all flesh.
Those taken away were destroyed. Peter explains how the survivors of the flood were brought safely by God through God's judgment.
1 Peter 3:20
.....who once were disobedient, when the patience of God kept waiting in the days of Noah, during the construction of the ark, in which a few, that is, eight persons, were brought safely through the water.
2 Peter 2:4-5
For if God did not spare angels when they sinned, but cast them into hell and committed them to pits of darkness, reserved for judgment; and did not spare the ancient world, but preserved Noah, a preacher of righteousness, with seven others, when He brought a flood upon the world of the ungodly...
...and the author of Hebrews states,
Hebrews 11:7
By faith Noah, being warned by God about things not yet seen, in reverence prepared an ark for the salvation of his household, by which he condemned the world, and became an heir of the righteousness which is according to faith.
Noah and his family members were spared. Noah was the heir of righteousness and he remained behind. The rest were destroyed, taken away by the flood. Therefore, the reference to "
the days of Noah" is NOT about the rapture.
Read and re-read the Genesis 6-9 text and the passages mentioned above for yourself and see. Then, once what the scriptures
state is understood, be on your guard for preachers who say Matthew 24 and Luke 17's mention of Noah is about the rapture. They are incorrect and their teaching on end times is not to be considered accurate.
However, it should not be necessary to read the account of the flood to understand their error because Matthew 24:9 and 24:29 say the disciples would be "
handed over to tribulation," and they would see "
a great tribulation." They would experience it. They would see it. They would not be raptured off the planet before it happened. Notice also verse 29 states "
a" great tribulation, not "
the" great tribulation. The text states it would be like nothing before or since but what, exactly, does that mean? If the "great tribulation" leaves more than eight people alive on the planet, then it is not worse than the flood

. Some end-times teachers say one-third of the Jews will be killed in the tribulation. Aside from the antisemitic nature of that claim, let's look at the math. There are currently a little over 16 million Jews in the world. That's in the entire world, not just in Israel (there is less than 7 million in Israel). If one-third of 16 million Jews are killed during the great tribulation that would come to 5.3 million Jews.
That is one million fewer Jews than were killed during WWII

.
So... either the teaching saying a third of the Jews is wrong, or a bunch more Jews have to be born so the population gets up to are 21 million (which is not likely to happen in your lifetime or mine), or a lot more than a third of the Jewish population is going to die.
Or, perhaps Jesus words, "
such as has not occurred since the beginning of the world until now, nor ever will," is intentional hyperbole on his part. After all, he did say it would be better to cut off your hands and poke out your eyes if they cause you to sin.
The point is this:
Read scripture exactly as written and on the occasion scripture requires additional interpretation then use other scripture, not post hoc arguments and extra-biblical doctrines.
The words, "
this generation" mean this generation and not that generation. Regardless of how and what happened; it happened in "this generation." Read it exactly as written, accept it exactly as written, believe it exactly as written, form your end times view to exactly what is written exactly as written, and be vigilant for those asking you to read scripture differently than what it actually states.
