Just like how people born female can put medicines into the vagina for absorption, bottom surgery of a person born male also works.
I think that this poster might be referencing how vaginal estrogen can be delivered as a pessary re a medicine into the vagina? Or possibly lubricant? The latter could relate more to a neovagina though lubricant is not medicine. But neither remotely supports the claim that a neovagina ‘works’ like a vagina.
Bearing in mind how easily convinced my own diagnosed autistic young adult is, what I see is a lot of grooming. All this talk of hate too. The language is very black and white/childlike. Either the writers are the young and gullible, or they are adults with a motive.
For this particular poster, I’d opt for achingly young and tragically susceptible trying to educate us. We cannot, however, blame these young people for their distorted beliefs. These vulnerable children and young people have been subjected to years of horrendous grooming. Not only by adults with a deeply unpleasant motive (and there are always been men with fetishes), but they have been repeatedly lied to by educational and healthcare so-called professionals. Those groups are absolutely culpable.
