Everyone should have the choice to eat however they choose. Personally, I eat meat. I like meat. I try to eat ethically raised meat, but sometimes, I'll get that diner cheeseburger and I like it. I'm fine with those who choose to go vegetarian, but some people take it too far and become fanatical. Nobody likes an extremist.
Take this recently-turned-vegetarian mom, who has decided she's going to make her daughter be vegetarian too -- just in time for Thanksgiving. Yes, I too have a vegetarian sister who makes dinner out of side dishes. Which ... good for her. More turkey for the rest of us. But why you'd impose dietary extremes on kids is beyond me.
