Single sex spaces aren't something until the supreme court ruling that have ever existed in law.
That is flat out wrong. The SC merely clarified laws that already existed.
Trans people have always had the right to access spaces appropriate for them
Yes. And when there are different spaces provided for men and women, the SC have clarified that the appropriate space for trans people is the one for people of their sex.
You seem to believe there is something meaningfully different about trans people, not just in their own self image but out there in the real world. Something that is also meaningful and recognisable not just to the trans person but to other people as well, a material and empirical difference between trans people and others of their sex such that what is appropriate for everyone else is not apropriate for them. Not just not desirable for them but actually objectively not appropriate for them.
Can you explain to me what that is?
What is different between men who claim to be women and all the other lovely men who are no risk to anyone, that it is only the men who claim to be women that you consider to be appriopriate for women's spaces?
Can you explain to me why the self image of men who claim to be women based on something they claim to see in common between themselves and women should be more relevant than the self image of women who do not recognise whatever it is the men who claim to be women believe they have in common?
Can you even explain what I should be able to recogise in myself as a woman and also in men who claim to be women?
Can you explain why it is so wrong that female people, who have been oppressed, disempowered, overlooked, belittled, exploited and abused by others who see that they are female, and whose self understanding is shaped from birth by that experience and by the understanding of what "woman" is within our society in ways that people who have male bodies is not, should have spaces and protections, a political voice and cultural recognition of our existence, our history and our challenges?
The law also doesn't compel places to exclude trans people thankfully. It would be totally unenforcable without invasive medical testing anyway...Nothing anyone can do to stop that.
I'm sorry, I don't understand this. Why is medical testing required? Trans people know they are trans. They know their sex.
Are you suggesting that trans people will carry on selfishly violating and thereby destroying single sex spaces even knowing now that it is not appropriate for them to be there, simply because they want to? Even knowing now that many women in particular do experience trans women's presence in their woman-only spaces under the pretext of some sort of common "womanny sentiments" not an act of solidarity and shared sisterhood but as an extremeely male-gendered act of intrusion and abusive power play, they will continue to do this?
You really believe that the only way to make trans people behave like respectful human beings is to have to enforce it on them?
I mean, wow. For someone who claims to like trans people you don't seem to have a very high opinion of their integrity!
Do you feel the same about all laws? If we can't active enforce a law at all times at or before the point of the offense occuring there's no point in having that law? Rape is hard to prevent and hard to prove. Maybe that should be legal too? How about racism?
Incidentally, when you speak of enforcement I'm not sure you understand who is committing the offense. A trans woman in a women-only space is not automatically at legal fault (moral yes, but not legal). If he leaves when challanged with no fuss it's unlikely to go anywhere.
It's the service provider who may be at fault, either of direct sex discrimination against men (having a "woman only" space is illegal due to sex discrimination against men unless it meets the EA exemption rules) or indirect sex discrimination against women if it can be shown that their "woman and men who want to be there too" policy is disproportionately disadvantaging women (female people).
The only reason the trans woman himself might find himself foul of the law in a women-only space, service or activity is if he does not leave when asked or if he makes a repeated pattern of it, in which case he may be breaking laws against voyeurism, indecent exposure, harrassment and suchlike. These are not laws that have anything to do with being trans, these are just laws that have to do with treating our fellow humans with respect and decency and apply to everyone. The "crime" is not in being trans, but in being a man knowingly entering women's spaces and refusing to leave or acting in ways that causing distress within.
My friend owns a pub and will not be excluding trans people from the loos. My women's hiking group will continue to welcome our trans members.
Your friend and your group are on dodgy ground - as above it they are likely falling foul of the law by discriminating by sex without the protection of an EA exemption.
I'm sorry to go on as I'm sure you are a nice person and feel piled on, but you have unwittingly signed up to suppot a very toxic way of thinking about men and women and some very toxic views about whether women (female people) have any right to say who we are and what we need, so these things need to be said.
Women are important, the voices, rights, needs and experiences of the female sex do matter, and we can't just hand wave it away and be gentle to you just because you are probably doing it with fine and noble intentions.
