@isi @sylveon It's kind of implicit that when talking about something relating to a subculture that it would be referring to people involved in said subculture, and not everyone. Like if I was to talk about how some people prefer to suck dick and other people prefer receiving anal, it'd be safe to assume I'm probably only talking about people attracted to people with dicks. Or if I was talking about people who prefer to ollie oop their sports ball compared to people who prefer to slam dunk them, I'm probably only talking about people who play sports ball games.
Aside from that, the dom/sub terminology does have some use outside of bdsm. Some people are naturally more "dominant" and others are naturally more "submissive" than others, and the terms sometimes get used in those contexts. But that's more like an active vs passive or "alpha" vs "beta" thing than actual dom/sub stuff.
Of course, like any other fetish, some people get a bit too caught up in it and try to force it on everyone else. So, yeah, that does happen. And like anything else, it's annoying and gross. I get pissed off when I see people forcing kinks I have myself onto other people, so it must be even creepier when it's with kinks the person doesn't even have.
