Two weeks after violent clashes in Charlottesville, Va., and one week after violent protests in Boston, another clash is shaping up to take place in Berkeley, Calif.

The well-organized, militant group By Any Means Necessary (BAMN) is rallying forces to “shut down” a planned march against Marxism in Berkeley. Berkeley has already been the site of repeated instances of political violence this year, predominantly by aggressive anarchist and Marxist actors.
