Thing is there's going to be no impact on women's safety like now really, let's be honest here, if there's a guy in the women's changing rooms and he's challenged and let's say he goes 'I'm a woman', but dressed as a guy, with a guys ID and so on then it's common sense really and should be dualt with apportly
Assuming you mean dealt with appropriately I think I should address this. Yes common sense should prevail but the lobby groups have ensured that it doesn't and that service providers are too frightened to challenge.
I am clearly a woman. I have short hair which may confuse, um, nobody, because I am clearly female. I am short, I have curves, I don't grow hair on my face, I have a high pitched voice. I have said to several people "I am a man" or "I identify as a man" and been given access to male spaces. Now I don't cause a threat in there, because I'm a woman, but there was no check as to what I meant or how I could possibly, with my woman body, woman voice, woman clothes, be a man.
These things already happen and there are no challenges.
The guidance given by Stonewall et al is wrong, and has created these situations where staff and customers are frightened to challenge anyone who says they're trans and accesses opposite sex facilities. The encouragement for anyone who says they're trans to be accepted as such is madness.
And it's not just about attacks - though these frighten me - it's about male behaviour and the male gaze. One man in a women's space will change the feeling in the room entirely. Perving at women, making them feel uncomfortable is pretty normal behaviour for men and we have spaces where we have respite from it. Why are people trying to steal them from us? Particularly to satisfy a group with a disproportionate number of fetishists?
