>>3878730There are threads where infighting occurs, and threads that are obviously present. It isn't impossible for both to exist.
>>3878729Many infographs are posted and people take them as fact. i.e. "Look, these people are x! And they said y! Burn them!"
As for infighting and echo chambers, see what I've said above. They can both occur. Think of people posting about white nationalism, and everyone all agrees that it is great with no opposition. But then someone posts about Americans being "mutts" and then everyone starts fighting and pulling shit out of their ass and wishing death upon each other all over a stupid ms paint drawing.
