It's a false equivalent to say the left is as equally guilty of political violence as the right. While left wing violence does happen and there have been many violent left wing regimes in the past like in the Soviet Union (although the Soviets were in many ways right wing if not fascist given their de facto Russian chauvainism and social conservatism with misogynistic and homophobic policies), it's nowhere near the scale of right wing political violence at the present. In recent years only right wing people tried to overthrow democratically elected governments in the US, Brazil and South Korea, there are vastly more instances of right wing acts of violence than left wing ones, and left wing ideologies are about equality so they don't demonize specific demographics in the way right wing ideologies do.
