Do you have time to talk about our lord and saviour, Termux-X11 ?

Still better than that Swarovsky Antivitus

Communities as in what exactly?
The Community Hubs for specific games or various groups that people made?
In either case, it's probably better to intentionally stay out of there, since you know that you generally dislike the content there.
Or, you could try to find a user group that has rules and moderates content in a way that you agree with.
But overall, Steam is platform for video games, which are generally considered to be fun, so it is to be expected that other variations of "fun" will be present there as well.
