It is a "dear god" moment when you realise some of the issues.
In fairness, I think the vast majority of trans folk just want to get on with life in the knowledge that they won't be discriminated against in employment, or if they try to book a B&B or whatever. The trouble is, it is the extreme transactivists who seem to have got the ear of the people drafting new legislation - so for instance, the old gender reassignment certificates are being replaced by simply being able to declare, in any circumstances, that you are transgender. And this needn't even mean "wearing a dress" - there are men who "present as men" (Daniele Muscato, for example) who insist they are women. And if (when) the legislation goes through, anyone male-bodied, whether trans or not, will simply be able to announce "I feel I am a woman", and you will have no legal grounds to challenge their presence in a woman-only space (this has happened already in America, with one case of a teenage swim team who I think are now having to use the janitor's storeroom to change, because a "transwoman" with fully intact penis insists that "she" wants to swim and change in the communal changing rooms at exactly the same time the girls change for their scheduled swimming training).
