You really haven‘t understood the SC ruling have you?
I suggest you read up and gain a basic understanding of equality law, PSED, Health & Safety laws and avoiding discrimination against women by not providing adequate facilities for us before you embarrass yourself further.
Comprehension fail.
Trans exceptions may still be available in certain circumstances: Once it has been established that a single/same-sex provision is appropriate, the Act allows for exclusion of people from single-sex provisions on the grounds of gender re-assignment in certain scenarios, again where this is proportionate (and regardless of whether the person holds a GRC). Prior to this ruling, we would have understood this to mean an exclusion of a trans woman from a female space/service (this is the specific example given in the explanatory note to the relevant schedule of the Act), but now this exclusion would be of a trans male from a female space/service (and vice versa). In practice, this exemption was reserved for provision such as women's crisis support services. It was not used for toilets where trans people would have been expected to choose the most appropriate facility (this was a position to which many women objected and remains at the heart of the current debate around this case). It is not permissible to create a situation where trans people do not have an appropriate toilet facility to use. It is not clear that the Act permits exclusion from single sex toilets on the grounds of gender reassignment in a work context (as compared to service provision). This may be an area where we see further guidance and potential legal challenge.
"BTW, there’s no such thing as ‘cis’ - only women or men. Men who think they’d like to be women are still men. THAT is the effect of the ruling."
Lol, the ruling doesn't have the power to roll back definitions in the general sense only in specific circumstances. Definitions rely on social usage. I suggest you read up and gain a basic understanding of how definitions in the non legal sense are formed.
