My point is to contradict the notion that

I don't know what your point is.

It really is, in-universe. Almost noone knows this save other maiar. The wizards are perceived as men by most people, them being maiar is far from common knowledge.
But that’s just what all wizards are and always have been. It’s the only way to be a wizard. It isn’t, like, a hidden fact or anything. Wizard is a race not a profession. Like elf or dwarf or hobbit.
