Well, I would draw the line at saying that men and women who present as the opposite sex, or believe they are the opposite sex, should be executed, put in prison, denied basic human rights, simply because they choose to live this way. That is clearly going too far.
I believe that anyone should be able to dress how they want, as long as it doesn't offend public decency. But that is where it becomes subjective, is any man dressed in women's clothes offensive? I would say not necessarily, but a man in full drag, or dressed in fetish gear, including dressing as a small child,baby or animal? Yes I think that is offensive and should be unlawful, but some would think that is too far. Possibly it is, and I am wrong on this one.
I believe that no biological man should compete in women's sports, win prizes for things like 'woman of the year' use female public toilets and changing rooms, be housed in women's prisons, or be recorded as female in any official document. To me this is just common sense, but to some these are too far.
I don't think public money should be used for any gender reassignment surgery, ever. I think that gender affirmation as a treatment for gender dysphoria should be banned for people under the age of 25. I think that anyone who wants gender reassignment should have to pay, source and arrange it themselves, and not be entitled to any treatment arising from this treatment, such as infection treatment or ongoing HRT, on the NHS. I am aware that others will think this is an extreme view.
