Nitpick: This may be true of “folx” and “Latinx”, but “womxn” (despite sometimes-similar connotations) seems to have originated as a way to highlight/signal feminism, and has only acquired queer connotations recently.
Edit: Wikipedia traces "womxn" back to the 1970s, but it seems unlike "womyn" it didn't get much currency in ordinary feminist usage, only finding purchase when the queer angle was added.
