It's not a monster under the bed at all, the pot was limped.
6WWW is a standard limp for just about everyone on the button.

This is about the worst case scenario you are going to find here, no? If this was the case then you would be correct in at least check-calling a PSB on the flop.
Everyone seems to be ignoring the fact that villain will often (very at these stakes) have A2 w/spades or at best a naked 6 (than we can catch up to with a spade). If you fold your AA hand every time the board pairs you should pick a different game.
And yes, I think we are all in agreement that this is a must pot preflop.
