Nobody forces anyone to get vulched. I don't see how it's even an argument. LONG ago, a single CHog could de-ack a field, then hang around and vulch. In the context of the MA, that would be called, being a noodle. However, still completely "fair". Now though, not so much. I'm sure it happens, but not often. Hell, it's next to impossible to get 2 or 3 out of 10 buzzing a field to actually try and kill ack. Sure, some people will take advantage of a field take and vulch for no other reason than to vulch, but it's no different than using other's as bait or cherry picking a furball... exact same thing. This is NOT the DA we're talking about.
In the MA, if you're red, you're fair game, end of story. Anyone and everyone is free to THINK otherwise... but they would be wrong.
