When most Americans had their introduction to antifa, or anti-fascist, groups, it was an overwhelmingly peaceful collection of disparate peoples who opposed the white supremacists rallying in Charlottesville. In that setting, they appeared docile.
This past weekend, though, groups waving the same banners in Berkeley wreaked havoc on the streets. Their violence was unwarranted and largely against peaceful protesters, or in some cases, random people in their path. In many ways, these are people who simply crave violence, and inject it into the ideology du jour.
All political violence is dangerous and unnecessary. Sure, certain antifa groups have been romanticized as opponents of the so-called fascists of the far right. This certainly does not legitimize militias from the left appearing on the streets to meet them. Our taxes already fund those who should protect us: the police.
Another troubling aspect of antifa is their politics — or lack thereof.
Just as plenty of upstanding conservatives loathe any association with the alt-right, so should liberals shed affiliations with the militancy on the left. Antifa is not a collection of moderate Democrats in costumes; they are cabals of anarchists and communists.
