You don't say what stakes you are playing at, but I think you will always find people who will call a raise with anything. AK is a drawing hand but a strong one. Pre-flop you raise it for value and re-raise to try and isolate and get HU with the original raiser. Yes, it's hard to play if it doesn't hit the flop, but that doesn't mean you don't raise with it pre-flop. Maybe you need to look at how you are playing AK after the flop?
