In what way does anti-fascism imply anything other than anti-authoritarian, least of all pro-communism? This guy I linked below when trying to understand your comment even questions if it can be considered a "group" at all ( "I also question whether antifa can be considered to constitute a “group” at this point in time"), and I agree. Either way, equating far-right violence (which was responsible for every extremist death in 2018) and violence associated with antifa, for example against people like those at Charlottesville, Neo-Nazis, Neo-fascists, and white supremacists, just seems deeply disingenuous to the point of trolling.
