The problem with the left is its tendency to overreach. It always backfires. Who cares if some guy dressed in a costume? Are we going after all the war re-enactors next? If a guy ever played a part in a movie where he wore a confederate uniform is he fair game for denunciation?
The left hunts down people to its own harm, just like the right. Meanwhile the majority just wash their hands of both because of all the petty squabbling about who is more upright.
I have news for you- neither the left nor the right are upright.
