So you want trans women to use the mens toilet and trans men to use the womens.
There is no issue apart from imported culture wars from America.
As you can see from the original post you quoted, I support trans rights, so I don't understand why you're taking this tone with me.
This is a complicated, complex subject and we will only come to a reasonable resolution if we can have a reasoned debate that takes into account the safety of women and trans people as well.
I don't believe we are capable of having these discussions unfortunately.
Are you happy with ignoring the countless women's groups who have raised concerns over this subject?
