I wouldn't refer to PETA as "radical". They are more of an established group of stuntpeople, and they're good at their stated aim: to get attention at any possible situation. There the kind of group that enjoys people disliking them.
PETA workers, in their euthanasia enthusiasm, went to someone's house, took their dog off the porch, and killed the dog.
At least this group left his pet alive so he might be able to get it back.
A) that's not radical in the sense in using the word. 'Radical' doesn't mean annoying.
B) PETA does a lot of unpleasant stuff that nobody else does. In the case your're referring to the organisation were requested by a landowner to sort out the stray dogs in the area that were mutilating his cows udders. They were told that the trailer park did not allow dogs running free, so sadly they did not consider one of the "strays" was a actually a beloved pet, especially as it lacked a collar etc. the owner of the dog was not home, but other residents were around and gave permission for PETA to do their shenigans. PETA screwed up, sure, and the organisation admitted it. But is the human error of two PETA workers comparable to the very real problem of the proliferation of strays that are created by the pet breeding industry and inadaqute neutering programs. People who are angry because PETA euthanise animals are being sentimental and lack perspective.
