Man, that’s just appalling. Unless, I suppose, that you think people do not as a matter of their true nature adopt a different approach to their gender than is listed on their birth certificate. Unless, that is, that you do not believe our perceptions of ourselves and the world around us happens at the level or our brains. And unless you are convinced that any deviation from an accepted norm is a matter of choice. If that’s what you think, oh well. What I see are people trying to live the only life they will ever have as comfortable with themselves as they possibly can.
