Controversial issues in freedom of speech?

Answer 1

The fact that people can still express their views, even if they support something that is clearly wrong. An example is the Skokie Affair in the 1970s, when a group of Neo-Nazis won the right to have a march through a suburb of Chicago where over half the population was Jewish and 1/6 of its residents was a Holocaust Survivor. The Supreme Court ruled that it was entirely legal, although in the end the march didn't happen. Other issues include people being offensive when expressing their beliefs, and the question over how far someone should be allowed to go to criticize the Government.
