You've lumped together the RM and Dispensationalism. They aren't the same and don't come from common origins.
That is incorrect. John Darby was the chief originator of Dispensationalism, Darby was Brethren and the Brethren were part of the RM.
And I did not "lump together" anything. This is now the second time what I wrote has been either misconstrued or misrepresented so I am going to ask you to take greater care reading what I post and not making assumptions nowhere stated. I detailed a rough evolution of change going from the methodism of Wesley and the similar experientialism of Whitefield to the RM and took a more encompassing view of the movement based on shared theological precepts and teaching.
The RM includes the CoC and SDA.
Yep. I included them. The RM was a much larger movement than just those two sects. Limiting the RM to just those two sects is incorrect. I explained how and why such a limit is incorrect.
Your criteria #1 (the church is corrupt and sect X is the true church) properly applies to them.
Yep. It also applies to all the other sects I mentioned. They all share those views.
However, criteria #2 does not. The CoC is predominantly post-millennial in their eschatology, and tolerates amillennial and preterist views.
That is incorrect. The SDA's historical position is that there will be a global crisis, after which Jesus will have a physical kingdom here on earth for a literal 1000 years after which the unsaved will be annihilated. That makes the post-tribulational but premillennial. That modern SDAs accept a more diverse set of views has nothing to do with what I posted about their origins and the roots of Christian separation from politics, social policy, and culture founded in the RM.
The SDA does believe in a future tribulation, but their eschatology is post-trib.
They adjusted their doctrines after the Great Disappointment. Miller predicted Jesus would return October 22, 1844 and when that did not happen many "Christians" left the faith, many Christians left the SDA, and those who stayed experienced distress. Miller proved to be a false teacher and a false prophet. SDA of the early 1800s is much different than SDAism of today. Do not conflate the two.
Nowadays a lot of Christians of many varieties are involved in politics..... and nothing I have posted should be construed to say otherwise.
They don't think Jesus is going to rescue them from an apocalypse.
Nope
The desire to return to a New Testament practice of Christianity is the defining characteristic of RM churches.
Yep
Dispensationalists hold to pre-trib eschatology (#2)
Yep
Immaterial. The thread is about Christians' getting involved in politics, not eschatology. Because of the apocalyptic vies of the RM sects they thought it was best to abstain from worldly endeavors and they included secular politics a worldly endeavor. That is the only relevance to eschatology.
but they do not view themselves as the one true church (#1), excepting a few fringe groups.
They did in their origins. Darby moved from the Anglican Church to the Church of Ireland and then from the Plymouth Brethren to his own sect he called the Exclusive Brethren. He thought the Plymouth Brethren failed to live up to biblical standards and they kicked him out/he left. He mocked them with the name of his own sect. 175 years later Dispensationalism looks much different and is accepted by many of the post-Reformation denominations, but it was not that way during the RM.
Pentecostals in particular..
Irrelevant to the point being discussed. I included them merely as a bookend to the history I surveyed.
The JW's are a wild branch off of dispensationalism (#2).
No, they are a cult. It's possible, perhaps even likely Russel was familiar with Darby's writings, but Russell was not building his sect on Darbyism. JWism is not a branch of Dispensational Brethrenism (wild or otherwise).
The LDS is not an offshoot of either group.
I never said they were. What I did say is the all the sects I listed arose during the period in Church history we now call the "Restoration Movement" and all of them shared views tied to their claims and their intent to "restore" the Church. What I did say is Joseph Smith, the founder of the LDS was a Christian prior to his starting a cult - and that is what they are. That is what I said. I did not say the LDS were an "offshoot."
While it has some Methodist influence, it has far more influence coming from the Masonic Lodge,
I could expound on the Masonic influence, too, but that is not made the restoration movement.
All of this applies to dispensationalism and pre-trib rapture belief. It doesn't really hold for the RM churches, who are only too happy to dabble in politics.

With respect. You have your facts wrong.
Dispensationalist nowadays are very involved in politics and social policy. Jerry Falwell's Moral Majority was one of the early departures from the old Darby-informed separation, and an example that was uncommon when it began but considered normal 40+ years later. If you are as old as I am then you watched it happen. Falwell and others were influenced by Francis Schaeffer's works. Schaeffer almost single-handedly awoke the evangelical Church out of a century of slumber unintentionally caused by the restoration movement.
That includes the CoC and the SDA.
Every statement I have posted can be looked up and verified. Don't just disagree with me. Verify your dissent first. Look up Campbell, Miller, Russel, Darby and the other early 19th century leaders. Start with their own words, not second- and third-hand reports. The information I posted is readily available and objectively verifiable. Darby, especially, wrote quite bluntly about Christians separating from politics. Read up on the SDA support of Temperance (a curious mix of involvement, disdain, and apocalyptic thinking).
