I agree, but sadly logic doesn't work to get people's attention a lot of the time.
I don't think that PETA's methods are good a lot of the time, but it does get them attention and it does get more people interested in their cause (no bad publicity yadda yadda).
I find, however, that people love to point out the stupid shit that PETA does, instead of praising them when they get something accomplished. Pessimists
