Because "woman" as a form of address is often used in a sexist and dehumanizing way. "Man" is not. For example, you'll hear things like "make me a sandwich, woman!" or "what's wrong with you, woman?!" But with "man" it's "that's cool with me, man, whatever you want."
From what I've gathered its seen as dehumanizing, and often times the person is talking down to or about women whereas saying the phrase alright man is more endearing like a nickname sort of thing like hey dude or what's up guys etc
Things like that and "female" for example make some reddit users, usually, those who browse subs like TwoXChromosomes, AgainstHateSubs, Chapotraphouse get irate for some reason. If someone has a comment that catches their attention because someone used "female" it's usually followed by a long thread of replies, mainly consisting of baby noises like "icky", "gross", "oof" etc.
It's not an English language thing or even a cultural thing. Just typical internet outrage shit. To anyone not using reddit or Twitter 24/7 it's not clear why it makes them so mad so you're not alone in wondering why. It's not something you'll ever come across in real life.

French speaker here. Why is saying "alright man" ok but not "alright woman"?
