P.E.T.A. (People For the Ethical Treatment Of Animals) has been around a while making life miserable for most decent folks with their hyped up, false stories of how we need to treat animals as equals and grant them rights that only we, as humans, should enjoy.

These assumptions are false and most of the claims they use to further their cause are not founded in reality but in some vegatarian clubhouse full of 13 year old girls.
