Cause it seems to me that many people here want to kill everyone who is higher up on the social ladder than they are

Can you explain? This doesn't seem to be the case at all. Maybe it's just that I'm a Marxist-Leninist and understand what other Marxists are getting at better.

I've read discussions people seemed to take seriously suggesting that millions to tens of millions of people in their country deserve to die

Do you have an example?
