"Never forget that everything Hitler did in Germany was legal" - MLK
On their Facebook page, they write:
In the past, many events were considered legal, which are cruel and wrong from today's perspective. It was wrong to burn witches. It was wrong to own slaves. It was wrong to kill Jews. It is just as wrong, that over 1,000,000,000 animals are killed for the meat industry each year (in Germany alone.)
Just as wrong.
This is what passes for morality nowadays.
Hitler (although no one knows why he became a vegetarian) probably believed that slaughtering pigs was worse than slaughtering Jews. So PETA is a hair more moral than Hitler.
