HN does get some genuinely antisemitic comments, most of which get posted by one or two serial trolls who keep making new accounts. We ban those whenever we see their latest incarnations—it's a whack-a-mole thing.
Edit: please see https://news.ycombinator.com/item?id=41071782 and https://news.ycombinator.com/item?id=41071809 also. I've replied in each place you posted this because people often jump to wrong conclusions about the community and it's important not to do that.
Btw, you don't need screenshots of HN comments. Anyone with 'showdead' turned on in their profile can read the original: https://news.ycombinator.com/item?id=41066729.
All: if you turn 'showdead' on, please don't forget that you did so, because we sometimes get emails from people asking "how can you possibly condone $horrible-comment appearing on HN?" when in reality the account has been banned for years.
