But anyone can choose what they are called. The trans person might be a bad example, as there is a clear reason there, but TR's name change is little different to the way an actor chooses a name that they think will be more popular. Or to take a political example, people do not continally refer to Tony Benn (real name Sir Anthony Wedgewood Benn). I CBA to google, and that might be a bad example if he changed his name legally, but the principle is the same. Part of opposition to TR's brand of hate is not to be like them. Part of which is applying the same rules to everyone, no matter where on the scale from decent human being to waste of oxygen they fall.
