I agree those things you mentioned aren't very popular, and possibly where you are the mainstream culture is different than where I am, but I don't see any of those things as counter-culture in the sense that none of them are opposed by the dominant culture. e.g. If it came out at work that you were a member of a group that fought with foam swords, had unusual sexual preferences, or were funny atheists, you wouldn't be fired. People might say "oh, that's weird" but they aren't going to hate you.

I'm not saying any of those things are bad (in fact, I like fighting with fake swords) but there's not hostility to them from the culture and they, in turn, are not hostile to the mainstream culture, so I just don't think they're countercultural at all.

By definition I think countercultural groups will strike you as weird and bad unless you belong to them specifically. Q-Anon, for example, which speculates that the leaders of society are <bad things>, is a countercultural group because they both hate and oppose elements of the main culture and are hated and opposed by it. The kind of antifa or anarchists who are attempting to burn down courthouses or police stations in Portland are another clear example.
