PETA always has been about killing animals. A 2003 New Yorker profile included PETA top dog Ingrid Newkirk's story of how she became involved in animal rights after a shelter put down stray kittens she brought there. So she went to work for an animal shelter in the 1970s, where, she explained: "I would go to work early, before anyone got there, and I would just kill the animals myself. Because I couldn't stand to let them go through (other workers abusing the animals). I must have killed a thousand of them, sometimes dozens every day."
That's right. PETA assails other parties for killing animals for food or research. Then it kills animals — but for really important reasons, like because it has run out of room.
So compassionate of them.
