This is a response to Merry Prankster:
For the purposes of the discussion on Abortion, a woman is someone who has a uterus.
For purposes of social interaction, people can decide what to call themselves. It is really none of my business what someone wants to call themselves.
For the purposes of competitive sports a transexual is, to me, the same as a woman taking illegal hormones to increase strength, etc. Sporting Federations need legal latitude to make competition fair through their rules.
As an aside, it is possible to have discussions without the use of vulgarities to describe transexuals.
