In theory, Freedom of Speech may be a prerequisite for a democratic society. But, for all practical purposes, when you are sitting in a round table full of people, you don't exercise your freedom of speech by uncalled for insults. For example you would not call your friends wife or mother - a whore just because you have freedom of speech. That is absolutely wrong and disgusting.

Does freedom of speech mean you can insult anyone? Would it be freedom of speech if you make a cartoon of some politician's wife and called her a whore just because you can?

This does not mean that it makes it OK for someone to come kill you because you insulted them, but it is something to think about.
