Jessica Mendoza at CMS, pretty sums up exactly what ANTIFA is. (Anti-Fascists Action) They're essentially a collection of far-leftists, Communists even, of course Socialists, and Anarchists. They're not the sons and daughters of the peace-loving hippies of the 1960s who were simply looking for their own way of life and tired of being told by their parents and others that this is how you should live and what it means to be a real American. Who finally decided to break away from the 1950s suburban dad works, mom stays home and raises the kids lifestyle. But instead wanted the freedom to be whoever they were and wanted to be even if that offended the cultural values of the older generations.
ANTIFA are more like the sons and daughters, grandchildren even of Tom Hayden, Bill Ayers, Jayne Fonda (when she wasn't acting professionally) Mario Savio, Abbie Hoffman, and many others. People who hated our capitalist private enterprise economic system, because they believed it was racist and left too many people in poverty. As well as our liberal democratic traditions that allowed people they disagreed with to speak out and allowed for right-wingers to organize. Who hated the American system so much that they felt the need to try to destroy it and even use violence to do it.
ANTIFA are not the Bernie Sanders-Jill Stein peace-loving Socialists of today who simply want to bring social democracy to America and combine it with our private enterprise system. But instead are people who again like the New-Left of the 1960s, who hate our capitalist private enterprise system, as well as our liberal democratic form of government, but hate racism and bigotry towards non-European-Americans, non-Christians, gays, women, so much that they'll literally by force even attempt to shut up right-wing groups.
Even right-wing speakers and thinkers who aren't necessarily bigots and don't hate non-European-Americans. People like Ben Shapiro who is a Jewish-American and proud of his heritage, but who does have homophobic views, but who isn't a racist. ANTIFA are people who claim to hate fascism and yet will use their free speech rights to try to physically prevent people they disagree with from using their free speech rights simply because they're offended by what right-wingers have to say.
I label ANTIFA as a collection of far-leftist and Far-Left groups, because that it what they are. They're a movement of illiberal (not liberal) political factions including Communists. People who are so diehard and hard-core with their political and cultural views and believe in them so strongly, that everyone else is not just wrong, but dangerous and offensive and therefor according to them don't have a right to speak and perhaps even live peacefully.
You could be a Center-Left Liberal or Progressive, or perhaps even a Far-Left Democratic Socialist, who doesn't believe in using violence to accomplish your political objectives and believe in free speech even for people you disagree with and you could get labeled by ANTIFA as a traitor and sellout to right-wing corporatists. To compare ANTIFA with Occupy Wall Street of 2011-12, would be inaccurate and perhaps even insulting. Because OWS of earlier this decade is the Bernie Sanders-Jill Stein social democratic movement od today. Who don't believe in using violence to accomplish their political objectives. ANTIFA instead are the violent anarchist wing of the Far-Left in America.
