PETA's Newest Ad Encourages Guys to Go Vegan Without Hurting Their Girlfriend . . . Is It Offensive?

PETA loves using sex in their ads.  Last month they released a weird "Girls Gone Wild" style ad where women flash the camera . . . but instead of having what you expect, they have COW UTTERS.
But some people think their newest ad is offensive.  It shows a girl in her underwear wearing a neck brace.  And the narrator, KEVIN NEALON, says that if your boyfriend goes vegan, he'll quote, "bring it like a tantric porn star."
