The worst attack on freedom of expression is political correctness. It is a form of self-inflicted repression and censorship. And it is caused by social fear.
For me, if you are politically correct, you are a poor wretch who don't dares to hold his gaze high and hides what he thinks. You are a sad sheep, a dog trained by beatings.
If people are running towards an abyss or everyone is shouting absurd slogans in unison and you remain silent and applaud for fear of being rejected and attacked by the ignorant mob, then you are being politically correct.
A total waste of evolution.
