Yes, the pre-trib rapture doctrine is nonsense, but so is preterism. Think: has Damascus become a ruined heap, yet? Has G-d drawn all nations against Israel to battle and destroyed their armies, with a flesh rotting disease yet? If so, when did it take 7 months to gather the bones and bury their dead? Has the mount of Olives been split in two yet? There are only a few of many bible prophecies that remain to be fulfilled and today seem quite likely.
I think you and I have come to some of the same conclusions! Gee, you mean I am not alone?:)
