No it would've just been mean and he goes to jail for 3 years for violating someone's safe space.

He's not the brighest bulb in the room, is he?

Good riddance, we need to keep that racist scum on check.

Your first argument (sister is a bitch) does not work because being racist is the catalyst for the reaction. If I know you are not racist and you say that, is it offensive? Nope. Probably funny. But if I am to believe you are racist, that makes for provocation. I am not saying he is racist, but what he said IS racist. No two ways about that. You cannot say he wanted to be a provocateur but he did not want to be racist when using racial slurs, in context, to be a provocateur. Unfortunately, you lose any, "benefit of the doubt" when you put yourself in that kind of integrity compromise. Again, I am not say he is racist because I do not know the dude, but what he said most defintely is racist. Especially using your, "spin" or context.

So what if he is Racist?

Not sure if it was a case of racism or mental disease. That was a little bit too weird.

As a German I often get called Nazi by many on the Internet when people are mad. But in most cases I think they only do it because they think that is how they can hurt me and not because they think I'm a Nazi. In this case he did maybe say it because he tried to hurt the other person and not because he has something against Blacks. 

Doesn't change that he shouldn't be a "pro player" in any team with such a behaviour. 

I wouldn't say that he's a racist or that it's a racist rant. He's just an idiot who raged, I've seen way worse.

Shouldn't be too much longer.
