Political correctness is one of the engines of nannyism. Allowing and even encouraging 'offensive' ideas is vital for the intellectually health of a free society.

Some say Google is God. Others say Google is Satan. But if they think Google is too powerful, remember that with search engines unlike other companies, all it takes is a single click to go to another search engine.
Fire and swords are slow engines of destruction, compared to the tongue of a Gossip.
