I am right in the middle....
The complaining woman had a point. A "transgendered" person is not a cross dresser. If this individual was as she describes, the intent of fair access has been breached. What is to stop anyone from donning bra and pantyhose and getting a cheap thrill. The gym needs a better policy on what constitutes access to the women's change room, or perhaps investigate a third change room if that demographic is so important to them.
On the other hand, she is an asshole. You do not go behind people's backs and campaign to get them tossed out, that's junior high crap. And if, as the story alludes, they received complaints about her they were right to take action, AFTER having addressed her about the issue.
Transgendered is the new issue, and it raises numerous issues. It takes a long time, I understand, to make the transition, surgery etc. Where do they go in the meantime and how should business and government react? This business reacted badly and left the impression that transgendered have more say than regular people, and that any old dude can dress up and join as a woman.
