It's not that I'm not willing to play the flop, it's that I don't want to play that hand against that much action post flop. On the button, I don't mind seeing a flop with a mediocre A-J against a relatively small 2.5x raise. If an ace hits and there's a lot of action before it gets to me, I can fold with a relatively secure knowledge that my kicker is no good (especially if the raise comes from a very tight player).

In this case, if the initial raiser's post-flop betting had been weaker, I would have played the hand much more aggressively, since up to this point he had not been aggressive at all unless he had a monster hand (on an earlier hand he had made a 4xBB raise UTG, then check/folded when an ace and a king came on the flop). But his half-stack bet on the flop was screaming that the jack on the board didn't bother him at all (I think the two hearts on the board scared him worse). Therefore, given the nature of my oppponent, I felt that folding TPTK was a good move, even with the flush draw.
