I did get that on the first few pages? still stuck on that?
I think you may have misinterpreted what (some) transsexuals insist/want.
After all, there are many, many women on MN who are post menopausal, have had hysterectomies and do not have share you...socialisation (whatever that is, there's bound to be some). Are they not women? apparently they are and are not up in arms at not being included in your definition. If you said all women have uteruses, or breasts, or can have children you would be wrong there, and you're insulting a lot of my friends and relations!
As I understand it, all (some) transsexuals want is for each individual to be able to choose how they are referred to, as individuals and if they want to be referred to as a woman, then they want that to go unquestioned and up for debate.
What is the point of you objecting to such a small % of people being included as women, anyway?
