Imagine being a teenage girl browsing art only to stumble upon White Kitten's gallery and then growing up 10 years later only to see men in dresses tweeting about lesbians and girldick.Meh, I think it's the cultural normalization of porn, as in internet pornography.
These men/kids are so obsessed with the objects of their obsession that they literally WANT to become "porn chicks". Note how so many tr00ns parody the kinds of traits one sees in women depicted in porn.
Add also the flagrant propaganda campaigns social media platforms are pushing on children in particular-- grooming them into the idea that "transitioning is the key to happiness!"
Girls who are exposed to this stuff often DON'T want to wind up being the women they see depicted in porn, so a portion of them decide "I don't want to be like those girls, so I must be trans!"
