My vegetarian friends don't hate me because I like a good, grilled rack of lamb. I guess that's a tautology, though, isn't it? If they hated me they wouldn't be my friends.
Quite a few vegetarians, though, I find to be as touchy, aggressive, judgmental and obnoxious as a lot of sociopolitical leftists. I don't know what they're afraid of, though such hatred always stems from fear, but they sure aren't people you'd want to invite to dinner, or to be around at all any more than you had to. Maybe they never read Burns and just can't see themsel's as ithers see them.
