@GottaLaff In addition, you can denounce the disproportionate police response in both cases. If the cops treated the students like they did the Nazis, a couple of cops would show up at the occupied buildings, politely ask the students to leave, and when they didn't, say ok, we really think you should leave, we'll be back tomorrow.
Not to mention "This is the real world," so the goals of the respective rioters and demonstrators should play an important rôle.
