No, the authoritarian right which includes US liberals. The left doesn't even exist worldwide except in extremely small insignificant numbers pumped up by media to create new red scare conditions among the population. The left has been crushed for the last 40+ years by the authoritarian right and has absolutely no backbone.
The authoritarian right runs the gig, the authoritarian right creates the violence.
Edit: DSA, arguably the USA's largest, most mainstream true left group is only ~65,000 members across the nation. Quite tiny. I've been to bigger soccer matches.
