I’ve noticed that both Blue Tribe and Red Tribe loyalists are often the first to attack protestors on “the other side.” Folks who vociferously condemned the Rodney King riots in 1992 were supporting the militia movement a few years later. Folks who cheered the Waco and Ruby Ridge massacres sided with the protestors during the Battle of Seattle in 1999. Those who despised the antiwar protestors during the Iraq War period were often first-in-line at the Tea Party protests. A lot of Tea Partiers detested the Occupy Wall Street protestors and vice versa. A lot of folks who were criticizing the anti-lockdown protests a few weeks ago are now saying the riots are understandable outrage, while at least some anti-lockdowners are calling for shooting protestors.
Of course, I’ve generally taken the anti-System line irrespective of where it was coming from. It’s one of the great things about being an anarchist.
