I am a person of color. I read those comments and got frustrated. I usually just comment/submit technical contents on HN. But recently I have been so pissed off by some obviously racist views that I commented with anger. My username is what I have used since grad school and now my company, so I am not willing to lose it unless there is no choice. Banning me because of this comment is fine. I don't want to be part of racist HN.
