Most people agree with new pronouns etc due to peer pressure. You haven't convinced them rationally, rather you convince them that it costs more to fight the movement than just fall in line. But a person who needs rational reasons to change how they speak will be much harder to "convince", since they wont change anything until they fully buy into the new.

The peer pressured group might think they did properly think it through, but mostly all you need is an appeal to authority and they fall in line.
