Isn't "folx" lingo or jargon? Like, let me explain a bit...
Just like "shade", "tea", and other queer lingo that was predominantly used within the queer community, "folx" was originally (in recent usage) a term that was used by some queer folk as a signal to indicate safety and inclusiveness.
But like "shade", some outsiders heard that jargon and started using it in communities where it wasn't common, and didn't carry the original intent, and so it looked confusing or annoying.
I think it's fine for communities to have vernacular words that are understood within their community, I suspect the real "villains" here to you are the folk who pull that jargon out and try to make it widespread.
