Find small communities.

In my experience, everything you said is 100% true -- once groups get big enough. But each of those points is, equally, 100% false for small groups.

For example, the Raku community is fairly small, so the r/rakulang subreddit is friendly. For that matter, even the [raku] StackOverflow tag is friendly! Last I checked, the same was true of the corresponding Rust tags, though I know they've grown a lot since I was a regular there.
