Ah the old, " Why don' t you just get it at the grocery store" argument. We all know that meat comes from nice little plastic wrap packages don' t we.

I love when anti' s try to use that argument. It' s so easy to shoot that one down. There really is no way to defend when you ask what the difference is. Especially if you throw in a comment about how they are paying someone to kill for them. Shuts them up every time.
A couple years ago a woman wrote into the local paper saying stuff about how can hunters kill animals when the good lord has provided supermarkets full of food.
I wrote back and pretty much said the same stuff you did. And I wasn' t the only one. Man, did she get it. There were letters in that paper about that for a good week.
It sounds like you handled it great. One for the good guys!
Good job!
