The whole group, maybe not, but there are as many, or more, racists as there are on the alt right, but the antifa members think it's ok to be racist in the name of "diversity", that it's okay to be racist against people of color who don't toe the anti-Trump line.
That was just one example. Don't forget the Jewish "civilian" who was beaten up and called a nazi by antifa /just in case/ he was right-wing, because he "looked white". Or the two marines who were put in hospital, after being attacked because of their military garb. The beating continued even after they identified themselves as Hispanic, only now the antifa thugs also started yelling "spics" and "wetbacks".
