Please don't take HN threads further into flamewar. You've done it repeatedly in this thread, unfortunately, and have even crossed into personal attack. That's not cool, regardless of how wrong someone else is or you feel they are.

We've had to ask you several times in the past not to do these things. Would you please review https://news.ycombinator.com/newsguidelines.html and take the intended spirit of this site to heart? We'd appreciate it. We're trying to have an internet forum that doesn't suck, if possible, and using HN for these acrimonious battles contributes to destroying this place. The site guidelines are the way they are for good reason and they need to take precedence.

Is that a quote? It sounds like you are paraphrasing your perception of someone's point in the least favorable possible way. If the guy really said "white people are tainted," then he might suck and I hope you pushed back.
