for the OP.
using the argument used (the man of sin can not be revealed until the one who restrains is removed)
the man of sin is revealed when he confirms a covenant with the many (mainly Israel)
thus, Pre-trib..
post trib is the most nonsensical belief of when rapture happens to me (who is left on earth to endure to the end and be saved, entering the kingdom age to repopulate the earth and be served by king messiah)
Amill (or whatever people want to call it, basically those who believe we are in the millenial age and have been since 70AD, there wil lbe no rapture and when christ returns, thats it.) is the most unbiblical belief, it rejects the literal interpretation of scripture. which basically makes prophesy to be of no value, God said in the OT, when he says somethign will happen, it will happen, He gives prophesy to give people NO DOUBT he is the one true God. He also said if any prophet makes a prophesy and that thing does not come true, that prophet did not speak from God.
what do I believe? I believe like I do in age of the earth (I am YES) that we will now when it happens, until then we can just speculate. and not worth fighting over. while somethings can be thoroughly refuted, Others can not, and we should not judge others based on those ideas or beliefs.
