Ehhhh, more like nobody wants to endorse the icky work and mindset you need to adopt if you actually want to reduce the number of people that abuse children. Nobody wants to have nuanced discussions about the problem because it's so revolting, but then you're stuck with blunt instruments, which are always worse.

Example: most people who sexually abuse children aren't actually sexually attracted to them. They do it for other reasons. Similarly, most people who are actually sexually attracted to kids never act on their urges. Also, they're nearly always miserable because they can plainly see their urges are abhorrent, so there's a lot of (valid) self-hate going on.

It's been a while since I read up on this, so the details are all gone, but the point being that in order to reduce child sexual abuse and get pedophiles the help they need (two related, but different things) you have to learn how these things work, and most people can't stomach that conversation. It often leads to solutions people find difficult to accept, like the fact that the sex offender registry does more harm than good.
