I have come to a realization. Biological men who suddenly decide they are women all has to do with the voice once they pass puberty and their testicles never descend. If they sound like girls, they decide they must be girls. The same is true for the opposite, with women who are butch no longer deciding they must be lesbian, but must now become men.
Remember back in the day when men with those prissy-ass voices would "realize" they were gay? Man, those were the good old days. Now, for some reason, they have to become women through whatever means.
And you know what is in the middle of all that? Cross-dressers. Damn, what ever happened to that old-timey kink?
