When you're too empty to care about or do anything worthwhile, you have to treat the few things you do have like they're fields worthy of academic study.
I suspect that's why these people are so obsessed with the idea of sex ed for children; if you're someone who isn't a retard the things you could imagine teaching to the next generation would be stuff like "Let them help out with gardening" or "Play some music with them" or at least "Watch the Planet Earth series and talk about interesting facts about animals", but if you don't actually do anything you're passionate about or interested in and are a degenerate who continues to exist solely because you don't have the courage to kill yourself, you turn to the chimp brained default of obsessing over your genitals.
That's all trans shit in a nutshell, in fact. Directionless people who feel isolated and out of control defaulting to the most primitive possible object of obsession.
