Does it have to do with you feeling that your intelligence or ability to understand is lacking or under suspicion? Does it have to do with being invested in a type? Does it have to do with how the questioner questions, as in phrasing and tone? Does it have to do with... what?
Why is it like an attack to some? Why does it bother you?
I'm curious, because occasionally the strength or vehemence of some reactions surprises and baffles me. I would really like to know, particularly from those who find it offensive or bothersome, what it is exactly about having your self-typing questioned or disagreed with that you dislike?
And I would prefer personal examples and explanations above speculation about others' motivations or reasons, please.
