The position that a general use of the word is exclusive is pure hogwash. It used to mean both males specifically or all people. Such ambiguity has been used as a club in the past to justify a male ideal. When we have inclusive options available, the persistent use of exclusive terms can and should be called into question. Just ask any English professor.
People use language.
Such use determines meaning, not scholars. Scholars, like the best news media, are there to report the facts, not participate in the debate. A feminist English professor would disagree with you. This just hasn't happened yet, and that is why this is such a hot issue for people. Study and dialogue has been going on for 25 years.
