It sounds like a recipe for a world of unfettered tribalism, where every space has explicit in-groups and out-groups, and nobody ever has to come into contact with someone who will challenge their beliefs, and where group shibboleths (even grievously false ones) are never corrected.
The world needs places where people can discover new information that goes against their beliefs. For people to be receptive to taking in new information, it needs to happen in a forum where there is a basic modicum of civility and mutual respect, where people are rewarded for taking down the temperature rather than flaming. Otherwise we might as well write down our 2022 beliefs in stone, as closed to future revision.
