Lots of women don't have 'functioning' vaginas if they can't have kids.a trans don't have a fully functional vagina you fool....all they have is an orifice where their penis used to be...birthing doesn't define gender / sex....you don't need to alter your body to become someone else...you can alter your body to feel like someone else...you are free to do that....now should you force people to believe what you feel? that's a big lie that you accept....you don't force people to believe how you feel...
You gonna tell them they aren't women too?
Unless you're now going to define a vagina as a place for penises.
Even then, you'll have to tell lesbians that their vaginas are no longer functioning.
You've never met any trans people, have you?
