Just dissonance.

The whole pedophile thing is more about demonizing political opponents than it is about protecting children.

So when you point out what is actually endangering children but doesn't demonize their political opponents, you've gone off script.

The goal in their nonsense is the dehumanization and demonizing. Undermining that goal with an appeal to the underlying realities of the thing they are claiming is extremely dissonant as they are effectively caught between a rock and a hard place.

So their reaction is anger and frustration and dismissal, as actually engaging with the topic in a meaningful way would necessitate abandoning the world view they committed to where their hatred for others is justified based on the righteousness of their cause.
