Who would have the authority to do this, and why should they be trusted? How could we get rid of them when they start hiding true things they don't want people to know about? What would their job title be? Minister of Truth? (I suppose you'd need to get permission from Orwell's estate to use that title, which is probably a sign that you should think twice about what you're doing.)
People who believe different things think that people with opposing beliefs are lies or delusion or lack enlightenment. I think it's better that everything is laid bare to the world so it's not hidden. But it requires a certain set of skills when consuming information.
I think Wikipedia is more like what you are wanting. It's curated, it attempts to convey accurate information without emotional language, etc. Of course, that's super difficult and it has it's own problem in trying to do that.
Trying to work out what are lies/truth gets super super murky when it comes to religion.
Not to mention people actually want to search for what people believe, I want to know what holocaust deniers think, I want to know what climate deniers think, that shouldn't be filtered from me.
But, it exposes a bigger problem about the problem of consuming information, how we, as humans, determine what to believe when exposed to everyones beliefs. Especially for people who are young and can latch onto ideas very quickly.
