Actually, the male attendee of the women only group is not necessarily the one at fault in this situation.
It is not actually known whether the male attendee in question genuinely identifies as a trans woman or not. They allegedly made no attempt to present as female and did not speak during the session.
What we do know is that when "Sarah" spoke privately to the rape crisis organisation after the session, to ask if there was a different group she could join which was strictly female only, she was told no. All their services are trans inclusive which means that anyone who self identifies as a woman is free to join any women's group. The rape crisis organisation refused to countenance designating even one of their groups women only, and suggested that "Sarah" seek support elsewhere. This being Brighton, there were no other organisations in the area which didn't have exactly the same policy.
"Sarah" is now bringing legal action to try to require providers of rape crisis services to offer the single sex support that many women need. Astonishingly, instead of just saying, "Actually, we hear you. You're a rape survivor and you're telling us what you and many other women need, we're a rape crisis organisation and we should be listening to you", they are defending the litigation on ideological grounds. Two male solicitors from the law firm Reed Smith are acting for them pro bono. Imagine you're a male lawyer and you're allowed to spend a certain amount of time doing pro bono work and ensuring women don't have access to single sex rape crisis support is the cause you choose to spend your time on. Astonishing.
In the meantime, "Sarah" has attempted to set up her own unofficial support group for female rape survivors. Trans activists got wind of this and some of them sent emails to every conceivable venue in Brighton asking them not to agree to host the group because they were anti trans bigots.
Meanwhile in Scotland, JK Rowling has set up and is solely funding a female only rape crisis organisation, which is inclusive of trans men and female non binary people as well as women, and will also offer trans women telephone support before redirecting them to more suitable services if they need face to face support. Ever since it was announced, trans activists have been trying to force the centre to accept trans women or be shut down.
So who is the oppressed and vulnerable minority in this situation, do you think?
