Well I've been banging on for months about the need for transsexuals to find their own collective voice so I'm really pleased to see this letter and I admire the bravery of all signatories, whether they have used their RL name, an online name they care about, or have signed anonymously. I hope this is the start of a truly effective campaign.
This is not our campaign though. The reason your letter is powerful is because all the signatories are male.
This is a TS campaign, not an add-on to the fight for women & girls' rights. TS have their own dog in this race. We will disagree on loads of stuff. Nevertheless there will be areas we can form political alliances (as opposed to being 'allies'). We can only do that if we acknowledge our differences, then agree to table them so we can fight together on specific issues.
So I won't say thank you but I will say well done 
Jaycee I don't know exactly what's gone on between you and sweary but I have also had a spat with you because you have talked about me behind my back. In my case you did it here on MN so it wasn't hard to find. You were given far greater leeway than any non-trans poster would have been given.
