"False doms" are, generally speaking, still dominant. They're just abusive. So the name really is some mollycoddling of language. A "real" false dom would be a switch or a full service bottom who through happenchance managed to get into a longterm relationship with someone more submissive than themselves that they're trying to satisfy by acting dominant for them, but don't actually wish to be the dominant party all the time.

Language matters, and even in niche fetish conduct, they STILL attempt to subvert it. Oh, they're not abusive, there's no need to report them, they're just a false dom, it's an identity crisis, not an abuse case!
