"Serial kidnappers that do not actually exist".
They absolutely do but RAINN says that the majority of CSA is committed not by strangers but by acquaintances and family members.
As for porn, yeah, it's not even simply a matter of it being more accessible. Kids and teenagers are capable of imagination and creating images in their heads. They're also capable of writing and drawing. I think the Netherlands had the best solution; sex ed should be early and comprehensive so kids will learn from it before porn gives them the wrong ideas AND ALSO to equip them to recognize grooming or abuse attempts.
"I reported it for being gross".
Cool. Cool. We need to face "gross" sometimes. I'm trans and thus many people find me gross. It's a visceral cognitive shortcut that we needn't rely on. Wisdom of Repugnance is a fallacy for a reason.
