think banning him is a bit harsh. A warning should be fine.
I also don't think he meant to be racist, he is just afraid something as powerful as gene editing can get into hands of wrong people. Not saying all chineese are bad.
I'm always happy to see community members reading others charitably, and I'm also happy to be wrong about any HN user's intentions (and unban or adjust accordingly). However, in my experience comments like this never lead anywhere good in the future, both in terms of their effect on threads and in terms of future output from such accounts. So we'd need a commitment not to post like this again to HN.
