I think that 1) people are so massively uncomfortable with the very idea of the reality of child sexual abuse that when confronted with it, it's just emotionally easier for them to turn away and try not to think about it, and 2) important men are valued more than children by many people.

That #2 is a harsh thing to say but I've come to the conclusion that it is true. It's hard for me to conclude there isn't at least SOME of that in this. When a woman is the perp they usually flay her alive before sending her to prison for forever and ever. When a powerful man does it, meh.

On the upside, people now talk about sex abuse openly and become outraged and horrified. That didn't happen when I was a kid. There wasn't even a word for it, and when people knew it happened, it was impolite to say so or draw attention. So this is better than that.
