Cross-dressers aren't transgendered or transsexuals. They're transvestites. Transsexuals have had or are undergoing a sex change.
Pretty fine distinction, I'm aware.
Sex changes are just mutilation. There is no change of
the genotype. They gotta get the other sexes hormones,
and they get phony surgical prostheses, or structures,but
it's all mutilation in the long run. It's the ambiguous
genotypes (the XXY's, or the XO, or the XYY's) that are
the ones with the confused "sexualities".
