I don't know about him, but "sexism" is not a problem at all in the real world. "Sexism" is a concept invented by cultural Marxists who openly proposed its use to disrupt existing cultural groups for the benefit of certain social classes (intellectual workers, etc.) and primarily exists in the modern business environment to make money for law firms. So, no, "sexism" is not the problem, the problem is "anti-sexism."
