dude what the hell... 6 million women children and men being systematically exterminated by decree from the government for 10 years is not an event. And the fact that it was codified by the nazi government means it was an institution.
I'm not trying to get into a pissing contest of who suffered worst. I'm just saying that both are black marks in human history.
I said its an event compared to Slavery.. You can't compare a 300+ year institution to a 10 year ordeal.. I've had shoes that lasted longer than the Holocaust..
On the other hand, you can't sit here and compare death camps to slave plantations either. It's commerce vs destruction/eradication.
