What do you think about the "two sex/genders, infinite personalities" thing transphobes use?

Personally: completely wrong, gender identity and personality are two different things, and use it like if GNC trans people (like me) doesn't exist.
I never disliked being masculine, play with the boys, be geeky, nerd, any masc-coded thing, I disliked the position where I was.
Also, they use it as a conversion speech: "no, you're not a woman, you're a feminine guy", or "no, you're not a man, you're a butch girl." Spoiler: if they present dysphoria trying to present themselves that way, then they aren't.
