Easy pickings. Take a look at the number of anti-Jewish and anti-West groups on the Left. When is the last time you’ve heard of Right-wing protesters interrupting a Left-wing speakers on stage? Code Pink and their like do this to Right-wing speakers on a regular basis (denying other people’s Freedom of Speech simply because they don’t like what is being said). I’m not going to name all groups, but broadly speaking there are a large number of Left-wing NGOs that only condemn Jewish and Western institutions while totally disregarding far greater abuses outside that scope.
And yes, this behavior extends into open racism (refusing to hire Jews under the guise of boycotting their nation state) and violent assault (physically assaulting supporters of the opposite political spectrum).
