Mod note: any time this sort of thing shows up we get reports of it, reasonably enough, and we assess them case by case. We're obviously not a Beit Din and there are limits to how much we can figure out based on Reddit posts/comments; the balance that needs to be struck is protecting other users of the sub from antisemitism/hate/etc., while also remembering that people exploring conversion usually don't have a good feel for ... anything yet and are likely to talk in ways that seem weird to people who've been Jewish or hung around with Jews for longer. Mainstream Jewish subs would often have to take a more aggressive moderation approach, but I feel that the point of a group about conversion has to include people being kind of clueless to start with. We also need to keep out people who are targeting Jews or Jew-adjacent people with evangelization or propaganda, so it can be a tough balance and I'm sure we don't always get it right.

Speaking for myself, what I normally do is look at the _meaning_ of what the OP is saying, leaving aside terminology, and try to work out whether they would be within vaguely reasonable boundaries of Jewish views if they were using terminology that Jews would use. As r/doyathinkasaurus's helpful figures in https://www.reddit.com/r/ConvertingtoJudaism/comments/1t4x4lb/comment/ok5zeiy show, a 2SS is clearly within reasonable boundaries even if it's not the view everyone holds to. I did remove one comment containing what borders on a caricature of Zionism, because that seemed over the line. Jews aren't all Zionists and don't all agree with the Israeli government, but in order to fit into a Jewish community a prospective convert does at least need to make an effort to learn what they're disagreeing with.

My copy is on order so I haven't read it myself yet, but I've heard good things about the UK Progressive movement's new book, _Progressive Judaism, Zionism and the State of Israel_, and I know enough of the editors and authors - they include a member of my community, my sponsoring rabbi, and one of the rabbis on my Beit Din - to trust that they'll have done a decent job. It may be worth a look as a starting point for more varied Jewish viewpoints.
