I have thought the same thing when I hear very confident alt right arguments that there is an agenda to normalize pedophilia - then what act do they go to for blackmailing. Because you don't just normalize pedophilia and stop blackmail culture.

I don't think this has been thought through. My feeling is the argument would go something like "Well when they normalize pedophilia, they've won the world, and there is no need to blackmail anyone because they are in total control of everyone and everyone is a slave." However I think this would be a hard sell to those who thrive on blackmail - the entire CIA. Also it is just a sort of vague and weak argument in general.
