I agree.
There was a strange relationship between the government, stonewall and business/public bodies that resulted in this mess, thats little to do with law.
I remember reading a transcript of May addressing a stonewall convention early on in the government, she talked about LGBT and trans rights when stonewall were still officially lgb not lgbt.
Stonewall eventually did become LGBT, were getting government grants and endorsements, creating awards for businesses.
The government (May again) out of nowhere announced maybe introducing self id.
I can see how business, not wanting to break future laws, saw stonewall as a means to achieving that.
The government then backed away from self id, yet didnt think to say to stonewall that their awards were out of date?
Now we are in a position where people are claiming that single sex provision is unachievable when it was only 10 years ago they had to be trained to be trans inclusive.
If it can be ravelled without legalisation, it can be unravelled without legislation too.
