Why? People who are racist against Chinese people are still allowed to comment on HN, as long as they aren't making racist comments. And in this case Hoy's apparently racist comment was eight years ago; there's no evidence to suggest it's an ongoing pattern of behavior—unlike her other patterns of behavior on prominent display here, which add a lot of context to the main topic of discussion here, which is Hoy's interaction with Ghost. In fact, Hoy has explicitly rejected racism against Chinese people in this discussion, a step she wasn't willing to take eight years ago.
Claiming I refused to “explicitly reject racism” “eight years ago” is a loaded statement. You might as well accuse me of having refused to deny I was beating me wife. That would also be true. And it would also be dishonest and manipulative.
