If learning new pronouns was really that difficult, none of your peers would speak more than one language. This is just the way society deals with issues that are personal or to do with respect: you don't ask people why they use Ms., you don't ask why someone hasn't had children, you (probably) don't fistbump strangers, and you feel guilt when you forget someone's name. Similarly, in most of these cases, it's worse to be on the other side.
