Or, you know, you could just get over it and realize that gender in language is not the same thing as gender in people. There’s one African language, for example, that has 16 different genders.
Also, you are mistaken that linguistic gender doesn’t serve a purpose. It does and there’s a pretty extensive body of linguistic literature on the subject.
Fun fact; as with most of the other Germanic languages, English originally had three genders; masculine, feminine and neuter. They got stripped out of the language for reasons having to do with English history that are too technical to go into right now.
