Even if someone called me a "male" constantly it would kind of freak me out. They are theoretically interchangeable, but male or female just comes off less "human" I guess. If they choose to only ever say male or female then it makes you wonder if they literally perceive you as inhuman.

Oh wow, thanks. Nope, I won't call women with that word anymore

I mean I used to do it tons in the army, that was the accepted way to refer to the women. Like "hey where is the females bunk I need to drop something off to sgt jones"

I never meant it disrespectfully, can't speak for anyone else though.
