> grabbing Dad's phone
That will only very rarely happen. Do you actually know people that will just give you their phone so you can watch porn? For more than one minute? People are so addicted to their phones.
> it's not about the children
It's also about the children, but there surely are parties which use the process to further their own goals.
> I am tired of the intolerant being tolerated
That's not the right quote for this case.

They don't ask for it, they take it when you're busy or sleeping. Teens certainly weren't asking for Dad's VHS tapes or magazines when I was a kid. I suppose this problem is solveable, too, though. Mandatory biometric locks on every device capable of accessing the internet, why not?
> That's not the right quote for this case.
It is. These people are fascists. Their goal is to create a society where the government has a permanent record of everything every person is doing, monitored 24/7 so nobody can defy it. The point about tolerating intolerance is that by abiding such people, you allow them to create an intolerant society, thus it is prudent even in a tolerant society to be intolerant specifically towards those whose goal is intolerance.
