How many? How many men have raped women in hospital? How many men have impregnated women in prison? How many men have taken away women's sports for their own use and taken away their awards and scholarships? How many men have followed women into the bathroom and raped, gaped or filmed them?
I will take the stats for the last year.
Then you can explain to me how it's right for a man, who was convicted of rape, assault, even murder can "decide" he is a woman and get put into a women's prison. Then you can tell me the stats of how many of those men turn back into men like poof as soon as they are out of prison.
Now, you can explain how a man can "decide" he is a woman and take no hormones, have no surgery and at times play in the men's category, then when it's convenient for him, go and play in women's sports. How a man, who has a bigger heart, longer muscle fiber, bigger muscle mass, bigger lungs and every other male advantage, has a right to go into women's sports. Men who are almost always failures in their sport in the men's category.
If trans people want rights, let them get their own prisons, their own sports, their own gym lockers, their own hospital ward, shelters, rape crisis centers, "Lesbian nights" (leave female lesbians alone), spas and waxing salons. They may not "feel" like men (or women), but they are not the opposite sex either and sex based rights of women need to be protected. They are sex-based rights, not gender-based rights.
