Someone said :
Don't get the link between "youthism" and paedophilia, seems a lazy and dangerous assumption to make.
Neither lazy nor dangerous.
When the cult of youth is pushed as far as finding excuses for a 40 year old to sleep with a 16 yo who "looked 18", it is a direct road to paedophilia (understood widely as under-age sex, and not limited to prepubescence... there is no difference really with so called "Hebephilia" excuses)
That cult of youth has led to a cult of hairlessness which is promoting attraction to non-adult bodies.
The cult of youth has normalized the idea that sexual desire should stop in time and only be geared towards the youngest possible forms: any maturity of the body is perceived as decay.
Breasts have to be firm, gray has to be dyed, pilosity has to be strictly controlled, especially in women, faces have to be without lines, eyes have to be unmarked, noses and ears have to be hairless, women's (and sometimes men's) armpits and upperlips have to be obsessionally epilated, arse cheeks too, flawless facial skin.
And that only occurs naturally in... children.
The vision of "youth" itself as sold and marketed by the soft-porn industry is a fantasy, are artificial version of an innocent body waiting to be deflowered by a 65 year old fat film producer.
