ya gotta source on that one buddy? I remain skeptical that there even is such a thing as "objectively" on this subject, but every time I see someone trying to look into or tally this up the main social media platforms are slightly-to-somewhat more tolerant of fringe right views than they are fringe left.

A confounder here is that social media inherits a lot of american political bias, and america has no mainstream left. Right leaning people interpret center and even center-right positions as "leftist" but that doesn't make it so.
