Convenience. Many communicative norms, even things like standard goodbye/hello stuff, is engrained in cultures for convenience. Why should people have to think hard about the basics of interaction? Though as an autist, social norms have always been difficult for me, so it was just a minor speedbump on the road of life to learn how to not be awkward around trans people.

Though convenience is the same reason cliche Boomers/karens will complain about anything. They’re so privileged that any inconvenience is tentamount to an insult directed at them. So, when someone comes in and says, “nono, you have to do something different for me.”, all they think is, “I’m being inconvenienced, and for this thing I don’t understand, wtf!”

As usual, it all boils down to selfishness. Way too many selfish, close-minded idiots in the world.
