PETA is full of shit, to the point where you could probably safely take on the opposite of their position on any given issue and presume to be correct, generally.
Eggs may be full of shit... but Peta? That's too easy to say. Don't kill the messenger.
No, eggs are not full of shit, PETA is. It's a hateful organization that does not give a flying fuck about animals, only about fundraising.
