Sincerity and respect for a person's race does not take a backseat just because someone made racist remarks to someone else. I've been the victim of racist remarks and I'm white, that doesn't make it okay for me to refer to the other person by their race. In fact, it makes it WORSE.

Being tolerant of ANYONE using racism for ANY reason is not okay.

EDIT: The more I read your comment, the more it looks like you support racism as a means of retaliation to racism. This is why racism still (and always) exists.

Agreed.

No, actually it doesn't. That's really not how logic works.

This is an audience problem. This post was pretty clearly not meant to be an intellectual tour de force; it was a rant, and a step away from frothing at the mouth. The author doesn't claim to be perfect, nor is he. For an audience like HN, it's completely inappropriate, because it doesn't take into account our biases and worldviews; but I seriously doubt he expected to be on the HN front page.

Edit: Also legal action? Im sure his use of "dumbwhite motherfucker" in court will go over very well. Come on...

Oh hey, it's the rare explicitly stated ad hominem attack.

(Not that that's any better.)

So racial epithets are OK as long as you're targeting a group of people who have wronged you? Got it.

Not that it in any way legitimizes the vile things that were said to the man.

So long as you're talking about a group of people who have systemic, institutionalized power over you based on the colour of their own skin? Damn right they're OK. I hate to break it to you, but it's pretty much only white people that think race is no big deal. People of colour tend to get disabused of that foolish idea pretty damn quickly by reality.
