As usual,

Ratzi says it better:

"Political correctness seeks to establish the domain of a single way of thinking and speaking. Its relativism creates the illusion that it has reached greater heights than the loftiest philosophical achievements of the past. It prescribes itself as the only way to think and speak - if, that is, one wishes to stay in fashion. Being faithful to traditional values and the knowledge that upholds them is labeled inntolerance, and relativism becomes the required norm. I think it is vital that we oppose this imposition of a new pseudo-enlightenment, which threatens freedom of thought as well as freedom of religion. In Sweden, a preacher who had presented the Biblical teachings on the question of homosexuality received a prison sentence. This is just one sign of the gains that have been made by relativism as a kind of new 'denomination' that places restrictions on religious convictions and seeks to subordinate all religions to the super-dogma of relativism."
