Or else what? you'll be sending the gender cops my way? ;-)
I don't have the time or energy to search for everyone's favorite pronoun before talking about them. If it's someone I personally know or talk to on a regular basis, then I will certainly use their preferred pronoun out of habit. But I expect people to accept that some people just care less about their pronouns than they do. I know this is a hard to grasp concept in this day and age...
I don't want people to call me "buddy" or "bro" but I accept it when they call me like that because I respect their choice
I have never encountered a correction between "he" and "she", personally, because either the name or the appearance usually makes it very clear.
I admit that it's harder for some names ("Andrea" comes to mind, or "Kim") especially if you have never met that person, but these cases didn't come up in my experience yet, so maybe I just have a small circle of friends or something... ;-)
And you mis-read my comment, I didn't say I'm opposed to being corrected, but I expect people to accept that others might "mis-pronoun" them, and not expect everyone to first search their whole social media presence for the correct pronouns.
