As with many things, PETA is a mixed bag.
They certainly deserve credit for raising the issue of animal awareness. I think we can all agree that animals should not be treated cruelly and they have done much good work toward raising awareness of the issue.
However, I think that many (if not all) of us can agree that they have gone too far on many issues relating to animals. The ideal is to find the middle ground — the shvil hazahav. Eating animals is fine, but abusing them and killing them needlessly and for sport (not to mention abusing them) is wrong.
So, in short, PETA deserves both credit and blame.
