Transvestites do it for entertaining themselves by public reaction. Transsexual do it because they cannot stand the gender they were born as. Friendships accept people that are comfortable with all they are cradle to grave.

Humanity supports ignoring all anyone is cradle to grave and anyone objecting commits crimes against humanity building better tomorrows economically since genetics only sustains numbers alive daily here.
