The "be treated like a man" statement is most offensive. I'm not a man.
I don't necessarily want to get into a discussion about parsing words, but I didn't say I would treat you as though you were a man. I would speak with you like I speak with anyone, man or woman (or, if you prefer, when I talk with a man, then I'd say the same thing to him if he were a woman -- even if he objected and said, "I'm not a woman" -- to which I'd respond, "Well, no shit, but you are a human being").
What could possibly be objectionable or "offensive" about that talking with men and women in the same manner?
I agree with you that "[b]eing male is not the standard." The standard should be: "Are you a human? Yes? Then I'll speak with you like you're a human."
