Physical, social and emotional gains for TG persons.  Spreading outwards from London.  

But, what if the thought of going swimming filled you with fear? If the very idea of entering a changing room prevented you from exercising?

This fear of what should be a safe public space is something that transgender and gender non-conforming people live with every day of their lives.

In line with the GRA in the UK, a pre op without a Gender Recognition Certificate cannot use common changing rooms or open shower facilitie

Seems there is a thread missing in the law forum. Let me expand on my statement above, Transexuals not in reciept of a GRC and or pre-op shall not use common/open changing, shower facilities or dormitories, to avoid ofending other users or invite derogatory rhetoric upon themselves or invite threatening or abusive behaviour to themselves, think about it many swiming changing rooms and shower facilities would have mothers and young children present.

Many people just read the 'press for change' web site and the 'gires' web site, where they advocate a change in the law, and take it as a fact.   It is a right that transgender people who are undergoing supervised transition can ask for a seperate facility to be made available
