It says a lot about a group that has to hide behind some really stupid looking costumes to hide their identity because they know full well that the things they believe and say are completely wrong, unacceptable and won't be tolerated.

They know what they are doing is wrong so they feel the need to hide who they are.

They are cowardly to their own beliefs.

Because if they truly, honestly and passionately believed with all their being in what they thought and said ... they would never feel the need to hide who they were.
