You don't think it likely that a significant proportion of the loudest opponents are also vegetarians?

I love people who make silly counter arguments. Watched a hunter challenge someone protesting their hunt: "Do you wear leather?"

"I'm a vegetarian" was the entirely predictable response.

(Actually, I now remember it was the other way around. "Do you wear leather" was the next step after asking the protester whether he ate meat and getting the vegetarian answer. As if a vegetarian would go out of his way to avoid meat, protest hunts, and still not be aware where leather came from.)
