No.
(sorry by the way, I saw this question on the front page)
I myself am a part-time vegetarian (part-time because I do eat meat when it comes from an animal who's had a good life with enough space and who was treated humanely), but I know lots of vegetarians who don't support PETA, and I don't either.
Just because I don't agree with sometimes the views of PETA, but mostly the ways they try to reach their goals. I am too against cruelty to animals, but PETA is usually just digging a hole for themself, making themself more unsympathetic to the public, and achieving the total reverse of what they set out to do.
No, because theres so much more to PETA then becoming a vegatarin. I mean its good to become one but thats not the only thing. I would know im a member.
