On a post about Great Britains sex-based spaces laws that was painted as trans people being “banned” from public restrooms, I pointed out that they are not banned, they just have to use the ones that are for their sex.

Nothing incorrect there. 100% factually correct. Sex and gender are constantly spoken about as being separate things now, since sex is not changeable (despite what the person who replied thinks)
I was then permanently banned for “transphobia”:

Do they even understand what a phobia is?

Sex is not changeable. Your sex is hard coded in every single cell of your body. It can never be changed. No amount of hormones or surgeries can change your sex.
Notice how Mr. Science over here doesn’t have a single citation for this nonsense assertion.
Is that your PROFESSIONAL OPINION, Doc?
