Holocaust is a horrible event but people think that "holocaust" only means the Jewish holocaust. There is also the african holocaust,etc.
It is specialist to think that we are different from our non-human friends. PETA could have presented this idea in a better way maybe put more past genocides in history instead of the Jewish holocaust, but it makes a point. We need to make a change.
by the way...
Holocaust means "destruction or slaughter on a mass scale, especially caused by fire or nuclear war."
Disturbing pictures, but they should be seen.
