i think you may have missed the point of the comments everyone was making. their basic message was that losing a stack here was fine given the stakes. but the consensus seemed to be that you should not have slowplayed this hand in this spot.

most of the table limped in and saw a flop that came with two cards to the flush. and on this low mildly connected board, everyone was willing to call a flop bet. this is not a safe situation. or at the very least, you will get more money into the pot by playing it fast.
