I'm wtih rippy here - If you fold AK to this raise you're playing it like it's A2 (a bad hand unless you make two pair), and I'm guessing you don't even play A2. If you are folding to aggresion on this flop after raising with AK, you should not raise with AK.

Unless you have some sort of mega read that the guy is a rock and would not reraise unless he had top pair beat, you call here.
