Sweet. I'm really glad some other people dealt with that. I'm done arguing, (I'm sure he will quote that and mention me giving up). But there is one thing I will respond to.
I am white, but I am not privileged. I grew up with very little money, lost friends and family when I was young, and earned everything I got. I have friends who went through the same who are black. Except they don't see a difference between me and themselves in the way you do - we are all just people who dealt with some shit growing up. It's funny how racially charged minorities often show their own racist tendencies by treating everyone else like they are completely ignorant. There are white people who understand the crap that black people go through, at least enough to comment one one's actions (I know, we will never "fully" know, the way you will never fully know what it's like to be a Jew). Not every black person was smashed down their whole life, and not every white person was brought up with a silver spoon. That, my friend, is racist. And worse, it takes away from the legitimate arguments made by reasonable black people, much as this gentleman's over the top actions took away from the credibility of his rational arguments.
Anyhow, anybody else who wants to have fun picking apart arguments, have at it. I'll follow along, and maybe jump in here or there.
