Typical.
@Eleanor is giving you a sound bit of advice --a warning. She did not say you are without excuse. Do you not see the construction there? She asked, in essence, whether you believe that what Romans 1 says is true; because IF you don't, then you are without excuse.
IF nobody has any excuse that rejects God, then it is not saying that admitting that God exists via realizing his power and divine nature is equal to the gospel. It is only saying that his power and divine nature is evidence that renders nobody any excuse, if they reject that evidence.
I do happen to believe that the Gospel is altogether reasonable, upon realizing his power and divine nature, but that is a different subject.
But I should think that your self-deterministic worldview would willingly claim that one who admits to God's eternal power and Godhead would impress God enough that he would be compelled to also send him the gospel.
