Most research shows that anonymous accounts actually facilitate more conciliatory and nuanced discussions. The big issue in social media is that the moderates are attacked by both sides. They are often attacked more viciously by those of their own political persuasion that are even more to the left/right than they are. This especially occurs if they are agreeing at all on any point with “the other”. Obviously this has a substantial chilling and muzzling effect. Anonymous accounts have less face to lose in the real world if they take a more moderate stance. However, over time even anonymous accounts build social credit with the in-group of whatever ideology they support. This has many negative effects. One is that politicians get the most visible engagement on their posts from the most extreme followers and so the politicians themselves moved to more extreme positions because they think they don’t have any moderate support. Twitter is not real life.
