Recent protests have had retards running around in inflatable mascot costumes, because optically if they're tackled they can claim "OMG the cops are using excessive force against someone who was just dancing around having a good time!", nevermind that those faggots are just as aggressive as everyone else, and those costumes are a good way to smuggle weapons.

More recently, retards have been drawing pictures of characters fighting/killing ICE, whether it would make sense or not. The comic in OP is an amalgam of those, showing how counterproductive it is if they were up against actual Nazis.
