I know about the letter; I signed it, using the name I use on Mumsnet.
But not the name you were using on Mumsnet before it was published, Kay. Please be fair and open about it.
Before that letter was published in the Guardian, you had been posting on FWR as Ceinwen, a trans ally woman and not a transsexual. You only became Kay on here once that letter had been praised. Some of us were quite unhappy at the deception, as I'm sure you'll recall. And one of us - not me - was very upset to discover that you were the person mocking them on a trans forum with another member of that forum who also used to post on FWR.
Pages 8-12 of the thread R0 linked to above are informative for anyone who wasn't here at the time.

I'll repeat here what I said:
Here, I appreciate that someone has signed a letter that indicates transsexual persons agree with me on self-ID - and so I say so.
Here, I also unappreciate that the same someone has been posting on the forum presenting themselves as a woman ally of trans people but now tells me that they've actually been a trans person all along - and so I say so.
For good or for ill, I also have a particular beef with people who make emotive appeals to female socialisation on feminist messageboards and, when I see that playing out, draw attention to it. I realise that it makes some people feel uncomfortable and I also realise that I can be a bit of a hardliner about it so many here might agree when it's particularly egregious but also disagree other times and think I put too high a priority on it.
Also, to save you the effort of reporting this post and then withdrawing your own response to it as you did earlier, I'll be reporting this myself immediately after posting. It may stay up, it may not, but you don't need to bother.
