I've heard this before... and I just can't imagine a more immature and pointless comment on this topic.
It's not as if vegetarians just can't "man up" enough to eat meat.  It doesn't take a badass to eat it... it takes a mouth and teeth... fucking wow... I have those!
Personally, I'm not a vegetarian.  I rarely eat red meats, but that's because I simply don't like them.  It's not a moral choice... I just don't like the way it tastes.  I don't eat a lot of dairy, although I do eat poultry.
As far as moral vegetarians... I see where they're coming from, without a doubt.  There are some sickening sights to be seen.  It's usually enough to keep me from eating meat for 2 or so weeks... but in the end, I wind up having turkey sandwich and forgetting about it, unfortunately.
