I encourage you to read up more on the killing animals thing. They essentially do it out of compassion, because most of the animals that end up at PETA are cases shelters are not equipped to handle and thus require a higher rate of euthanization. Even our local humane society has a relatively high euthanization rate, but it's because most of the other local shelters are no-kill and so their worst cases get sent there. I am friends with serious animal activists and they critically support PETA, though are part of different orgs themselves. Like I said, they have made mistakes like any other large org, but I think they have been a net good for animal rights.
