one of the problems I see with self id is the removal of medical support for those with gender dysmorphia. ( if that's not quite the right word, sorry, I have trouble with spelling and I know there is a word that looks similar, without an m I Think)
Transgender people commit violence at the same rate as their birth sex.
There is also a question of how easy self id would make it for men to pretend to be self id. If we remove the gender dysmorphia diagnosis, and say it is based on word and belief alone, and accept that no surgery, hormones etc is required , then clearly any man could say they are a woman at any time. As was recently demonstrated by David? When he nominated himself for an AWS. It was only when Labour was told clearly that is was making a point about the nonsense of accepting a mans word that Labour removed him.
Self id can remove the ability to track what crimes are committed by self id people as it may be considered discrimatory to identify a self id person. This appears to be the case in Canada.
Self id itself isn't necessarily an issue however, it depends upon how it is interpreted within the culture of the country. Which is essentially the extent to which people will be treated as their chosen gender and the estent to which gender is taken to mean sex.
The current issues seem to be arising because they accepted norm of a few years back, where the typical transsexual person would choose not to push certain issues, has been broken and some want transgender in all circumastance to be accepted as the opposite sex. Including places where today SEX differentiation is used under the principles of the 2010 equality act . Which allows even for a person with a GRC in some circumstances to be treated differently to the sex they identify with.
Society changes today mean that a boy can say he is transgender and expect to use a girls changing room. Again stories are emerging of girls under pressure to accept a boy even when the boy makes them feel uncomfortable.
Personally, I think it is wrong to say that we need to prove there is a problem. I think the opposite should be true. The transgender community needs to prove that the rates of violence by transgender people is that of women's violence. They need to prove that they sightbof a male body exposed and staring at a women changing would never cause trauma or flashbacks to a rape victim. They need to prove that they have no advantage in competitive sports. I think they need to prove this as they are coming from the dominant group ( transmen seem to be quiet in these boards)
As a feminist I would be happy to support the transgender community to enable them to live their lives without discrimination and fear without the need to muscle in on women. However when I asked one on here recently how I could help, they shut up.
