Benefit? Indoctrination of the youth.
Just straight-up grooming.
I was so happy a couple of months ago to hear a local radio host openly state that anyone in education who wants to discuss sexual things with young children wants to have sex with them - and he said it multiple times (and is still on the air). I also openly say this on the few occasions I’m even involved in such discussions; every person who wants to discuss sex with a young child wants to have sex with a young child - there is simply no sound reason to do it!
