It's hard to put a figure on the actual number of trans people.
"Trans :
A term to describe people whose gender is not the same as, or does not sit comfortably with, the sex they were assigned at birth.
Stonewall uses ‘trans’ as an umbrella term including (but not limited to) transgender, transsexual, genderqueer, genderfluid, non-binary, agender, trans man, trans woman, trans masculine and trans feminine."
That right there is from the Stonewall website.
I wasn't assigned male sex, it was observed at birth (I am hecka old so I think mother dearest didn't know my sex until shortly after she gave birth). So firstly, I don't have male gender for a start, even if that is a thing (not sure if it is or not).
And let's say male gender is a thing, for the sake of argument. If it is, I don't want it. It's probably a bunch of sexist old bollocks based on not crying, being the main breadwinner and wearing badly fitting jeans (if I had to guess).
I'm some kind of agender, I think. The agender subtype I most closely identify with can be summed up thusly 'gender is a bunch of tedious specious sexist bollocks that I want no part of please and thank you'.
So I'm trans, according to the Stonewalls themselves - who knew?
