Repression leads to resistance. Censoring speech leads to more covert forms of messaging. Political correctness gives birth to more sophisticated forms of protest. A mysterious German artist calling himself Rosato has begun putting Burkas over the heads of female statues in the park to warn about the impact of Islamization on Europe.
A picture says a thousand words and these pictures communicate even more than that without violating a single law. They are a basic statement that even the leftiest of the lefties and the most politically correct of the correcters has no trouble understanding and yet the perpetrator of this artistic statement cannot be charged with a single crime.
This is what protest looks like in a totalitarian society.
