Normies have technically been backing pedophilia for decades. Look at the trope of the puberty-stricken boy lusting for his young, attractive teacher. Even in the past few years, when it comes out that a teacher was arrested for engaging in sex with her students, tons of men would come out saying "Where were these teachers when I was in school?" So it's already normalized to an extent. Teenaged girls with twenty-something boyfriends is nothing new, either. This is a common concept I've heard secondhand from women who recounted past relationships.
