Funnily enough. They just need to claim it's "protecting the children" and people fall for it.
The funniest part is that high profile criminal cases go unpunished very visibly. Even if they have minors in their context, because the elite figures in question must be protected from the enforcement of rules.
I'd argue it works because it's a rhetorical tactic that's highly effective at suppressing dissent. Anybody sticking their head above the parapet is going to get painted as somebody who favours pornography over the safety of children, even though this legislation and opposition to it has very little to do with either.
