I had to complete a form to access online patient bookings etc..
It too asked for my gender. I complained and said it was inappropriate in terms of correct medical assessment.
And initially I got a good response and wanted to hear more from me and the person responding said they would raise it with their manager.
After that I got a one line response saying it was in line with accepted practice agreed by NHS England. They gave me the link to the document and I am sure I posted in on another thread here. I will try and dig it out.
And as others have said in the past no one had any problem with filling in forms where you were asked your sex.
The movement to blur the lines of the difference between sex and gender is part of the result of queer politics taking a foot hold in universities in the 80s, which led to women's studies being closed and gender studies being set up.
It is part of what is now obviously a long term campaign to change language to suit the desired outcome of denying the reality of biological sex.
This is why the NUJ was pressurised into stop using the word sex in news reports and replace it with gender (in the same way as they stopped papers from saying prostitute and say sex worker instead).
So the graduates from 80s universities who were taught (brain washed) into the gender choice concept went on to be researchers, journalists, MPs, teachers.
what we are experiencing now is the long term consequence of a movement that took hold in elitist but influential organisations so that they can then impose it on the wider population without revealing what their intentions were.
At least religious fundamentalists make clear that they are out to convert you.
Gender choice fundamentalists work behind peoples backs to gain positions where they can then impose their view of the world on everyone else.
