misgnedering

Accidentally calling a woman a man on the internet coz u didn’t know is not a big deal.

Calling people men by default is sexist.

Not advocating witch hunts but it's a bit weird to call someone a man if you don't know them. I see people on Tumblr a lot call trans women "man" and "dude" and then go "how was I supposed to know??" when corrected. Why make up genders for them in the first place?
