Fetishism and consumerism.

You're a teenage girl and you get off on fictional gay men, so much so that you wish you were one, and that has become a foundational part of your sense of self due to weirdo internet leftist ideology being so hortative of make believing and deviancy. You're also very into fandom and because young people are overwhelmed with how much content is easily accessible and not encouraged to develop any meaningful skills, including socially, or hobbies outside of media consumption, what you're currently consuming is also a significant part of your sense of self and how you relate yourself to others.

This is how you end up with an unholy marriage of these two aspects that borders on a manifestation of some kind of mental illness, that we are all forced to witness when we dare look up our favorite TV shows, books, and movies.
