I’m not even sure what to say to that. Other people assuming you are like them and treating you the SAME as they would treat all the other SO members is literally the outcome we want isn’t it? We’re being treated equally. But now people are being offended because they aren’t being treated differently based on information the other parties don’t have? What?
Try inverting your thinking - how would you like it if the only way you can get treated with respect is to allow others to assume you are something you are not? Its textbook alienation. On SO its likely not as bad as the rest of the net, but it'd be naive to assume its perfect: harassment aside, I imagine obviously female commentators get a hefty dose of mansplaining thrown their way
Fair enough if you call people out when they know something about the person they're interacting with. But you're suggesting people are prejudiced because they thought the wrong thing.
