Pullman's article is well worth reading and deals with the subject of loss of our liberties. Some extracts:
"Expressing an opinion is a dangerous activity
Whatever your opinions are, we don’t want to hear them
So if you threaten us or our friends with your opinions we shall treat you like the rabble you are
And we do not want to hear you arguing about it
So hold your tongue and forget about protesting
What we want from you is acquiescence."
