Have just been checking the mumsnet guidelines and this is what they say on the subject:
Will you consider deleting posts that associate transgender people with autogynephila (AGP)?
This is something we'd look at on a case by case basis, though we'll definitely delete posts which generalise.
So, we should bear that in mind here.
I wondered how anyone can say for certain that a man who identifies as a woman is NOT an AGP.
I suppose if he is seeing a psychologist or similar HCP then that HCP may be able to give an opinion. But the fact of the matter is, none of the rest of the people that such a man came into contact with would know for sure if he is getting kicks out of dressing as a woman.
The Equality Act, through having Gender Reassignment as a protected characteristic has given protection to men with autogynephilia, hasn't it?
I know this is not a particularly new trail of thought for this board but I felt perhaps it needed a bit of an airing.
