Whether it's a rage-click community, a community made for an agenda, or both, I don't know, but in either cases, I wouldn't see as surprising for the mods in such a community to be very trigger-happy. Best you can do, I think, is to block communities and individuals with such a profile, and to recommend others to not engaging (remember to explain why if you do it, btw).

You should also take into account the animosity against lemmy.ml in general from some instances and communities. Something to do with the moderation here or something else.

Nope, I just checked. Apparently, you can't say anything good about Linux. Seems like a useless waste of time but, whatever. If I got banned from that site I would consider it a blessing.

Tech people are always sensitive and unfair. You should get used to it or start seriosly fighting them if you're not afraid of getting in a legal trouble. As someone already said, it's probably good that you got banned because the community could hurt you more. Trust me, you don't want to get banned on a community you've spent years and made friends on.

As light rises, so does darkness to meet it

I read it as a jokey community and maybe you took it too seriously. Regardless that's a kinda silly comment to leave. That's a community for, ironically or seriously, hating Linux, so obviously it's not in the spirit of the community to leave a serious comment defending Linux.

I see a lot of Windows hate on Lemmy. If someone made a post here complaining about how much they hate Windows, and a Windows fan replied explaining why Windows is so great, I would say it's kinda heavy-handed but not totally ridiculous for a mod to ban them, since a Linux community is probably not for this person.
