The fact of the matter is that sex and gender are not the always the same. A man can be more feminine than masculine, just as a woman can be more masculine than feminine. Sex is physical. Sex is the body. Gender is the mind.
Gender is the heart, mind and soul.
Today, the same teachers who once taught that all homosexuals were deviants, now teach the theory of a social construct as thought it were an indisputable fact. The idea that anyone born male cannot understand what it means to be born female is absurd. Not every woman bears a child. Not ever woman menstruates. This is typically the last great argument against the acceptance of transgendered or transsexual women.
