Elon jumps around too much, but occasionally he comes down to the ground with a firm command. Today he declared that Twitterites who use cis as an insult will be treated as bullies and harassers, just like people who use nigger as an insult.
This is a major shift in the techtonic plates!
Eunuchs and castrati have been in government and drama and music for many centuries. They often occupied positions of power in the Ottoman and Mandarin empires. But they didn’t require everyone else to treat eunuchs as the default.
The defaulting of trans language is an extremely recent development. In 2015 nobody complained about ordinary scientific descriptions of plain old biology. The attempted switch hasn’t had time to become the majority norm, and some establishment scientists (eg Jerry Coyne) have been pushing back hard.
Elon’s enforcement in the elite social platform will assist the reversion to normal science.
