Why? Don't I have a right to free speech (on Facebook)?
Should it be moral for the government to set up small, limited, "free speech zones" far away from everywhere and say "If you want free speech, go here?". (Yes I know that has sorta happened in USA) What about requiring that all bookshops/newspaper sellers in a certain area only sell books/newspapers that don't mention $TOPIC. You're quite free to go to a bookshop 100km away which will sell you anything. Is that not a restriction on free speech?
