> Restricting the right to free speech does have negative consequences... from the development of critical thinking skills; development of technical skills; and limiting of educational information.

That's not true. Those things are limited in bubbles like the one of the rationalists as well, so free speech has nothing to do with why people don't develop these things. It's a matter of character; and obedience to a system that establishes the rules that evaluate social, academic and economic status.

The Supreme Court was capable of distinguishing between free speech and moron speech but the Party was too convincing.

Most of the parents of these kids don't have the required flow of information to handle their kids consumption. And more importantly, their stress levels are too damn high already. Which is also the result of the Party's long term strategy.

And if all the other parents say it's normal and the same for their kids, even those parents where it is not the case, which are those that know that's why their kids will be better off while everything collapses (vs making sure their kids are better off while nothing collapses), then there is no way but super-rationality to identify a problem and then there's the willpower to go against the accusations and the time required for researching strategies to deal with the problem while the rest of the world, and school, and one's own life keep working as they always did.

If there's bait, the untrained puppy bites. Unless the untrained puppy was trained to bite and puke it out afterwards to find hints at who put the bait right in the path of all those innocent puppies.
