Valerie & Cynthia. I am addressing this to you two as representatives of the two sides of this debate - but it is not intended as "Personal" because as you know I love you both dearly and count you both as friends.
What I am hearing from both sides in this argument is indeed as Cynthia observed fear. Both sides in the debate are passing like steam trains in the night because neither seems able to step outside of their own individual set of concerns and see things from the others point of view.
Valerie does not feel that she wants a third gender to exist because she fears being wrongly ascribed to it.
Meanwhile the non-op community fears that without a third gender they, as a small minority of people who do not feel able to conform to the current binary, are left without an appropriate identity.
The problem as I see it - is that people will wrongly ascribe one to all sorts of things anyway - it does not require the creation of a third gender for people to mislabel others and there is very little that we can do other than smile and put people straight. However the bottom line is that fear about our own identity isn't really a very good reason to deny someone else theirs.
It's a bit like me saying "well as an original BRITISH person I am fed up of continentals wrongly calling me an American, so I am going to fight and deny anyone the right to be American, because basically everyone knows that there are only two valid nationalities British, and Foreigners..."

Meanwhile the non-op and third gender community do have an unfortunate tendency to want to "include" people like Valerie (and even myself) who probably do not wish to be so "included." I certainly wouldn't wish to belong to any third gender...
And indeed then there is the whole can of worms which is the lack of any satisfactory FtM surgery at present...
For all these reasons this is therefore a problem with no solution and every time we debate this issue we will run the risk of people getting upset and tempers fraying.
All I can do is again appeal to people to realise that YOU are all individuals in your own right. You are NOT a label. So perhaps we should worry less about what other people are doing and more about what WE, as individuals, are doing.
This also precisely is why I don't generally join clubs, political parties, campaign groups, military groups, teams or indeed any corporate activity (unless I can be the leader and a (hopefully) benevolent dictator). There is just too much scope for some silly arse to go doing something, in my name, which I don't approve of, or agree with!
