Political Correctness is servility. It is granting in principle and practice that you do not have the right to your own perceptions and following opinions. You accept limits in both speech and behavior that you do not determine.
We are a horribly uninteresting society, in many ways. We lack genuine eccentrics. That is why people feel the need to dress in strange and ridiculous ways. They lack any means of differentiating themselves on the inside, so they do it on the outside.
