Unless you're a full blown vegan you have no right to criticize anyone for deer hunting. If you find it morally wrong, fine, that's your deal but unless you're a vegan you really have no room to speak.
As someone who has hunted since he was a kid, as someone who grew up on a farm, as in an actual farm, I can assure you, shooting a deer is a lot cleaner than any of the meat you buy at your grocery store..."cleaner" meaning, the manner in-which it was killed. If you have no problem eating grocery store meat, you should have no problem with hunting.
A side note: glad to know real people still exist in the world like the Warren's...I was beginning to think we were being surrounded by the Jersey Shore.
