How about names. Do you call Muhammad Ali still Cassius Clay? Just because that’s the name he was given at birth. Should people not have the right to change their name? Like it is here in Germany. And what exactly do you consider stupid about the pronouns them or they? I think they (!) are just normal pronouns, aren’t they? And for quite some time they are regularly used to replace single persons, if the gender of that person isn‘t known. I know that because when that started I was totally confused because I had learned different at school in the 70s.
