What you are saying here kind of sidetracks the actual problem those critics have though, doesn't it? The problem is not the acknowledgement of how bad child abuse is. The problem is whether we can trust the people who claim that everything they do, they do it for the children. The problem is damaged trust.
And I think your last paragraph illustrates why child abuse is such an effective excuse, if someone criticizes your plan, just avoid and go into how bad child abuse really is.
I'm not accusing you of anything here by the way, I like the article and your insight. I just see a huge danger in the critics and those who actually want to help with this problem being pitted against each other by people who see the topic of child abuse as nothing but a convenient carrier for their goals, the ones that have actually heavily damaged a lot of trust.
