All extremism leads to hate, whether left, right, or center. They just hate different people. It goes without saying that there is plenty of hate on the right. But, historically, the “left” has included The Terror period of the French Revolution, the Cultural Revolution under Mao, the purging of the bourgeoisie during the Bolshevic Revolution, and the vast pogroms and genocidal famine in Ukraine under Stalin. Being on the left of the political spectrum does not immunize a person against hate.
