Just love those words. This is far from where a majority of people/communities are going (IMHO). A lot do no like listening to a different or opposing point of view. They make all out efforts to gag, remove or execute :) In the slightly better form (but equally dangerous nonetheless) case, they make a charade of listening and do nothing.
BTW, these words were widely attributed to Voltaire, but cannot be found in his writings. With good reason. The phrase was invented by a later author as an epitome of his attitude. It appeared in The Friends of Voltaire (1906), written by Evelyn Beatrice Hall under the pseudonym S[tephen] G. Tallentyre.
