I am afraid you have confused transsexuals (those of us who are type IV or higher on the Benjamin scale) with genderqueers, genderfu--s, crossdressers and drag queens. I can assure you RuPaul and his ilk do NOT speak for us. [...]
The basic message throughout the "open letter"? Don't consider transsexuals as second class citizens because life is so difficult for them. But it's okay if you consider genderqueers, genderfu--s [sic], crossdressers and drag queens as such. (Presumably because life is a bowl of cherries for such folk?)
Yup. Basically, Sarah is requesting that Julie Burchill narrow her discrimination a bit.
Definitely a "fail", though.
PS I'm going to ignore that Sarah seems to think Julie Burchill is an employee of The Guardian.
Edit: I added the bit about difficulties; I was trying to add in a bit about "not because of equality or anything like that", but couldn't and not substantially change the post.
