Was my title yuckky? Possibly. I may have compromised my decency by typing that.
Freedom of Speech. Something the Internet has personified. Something some Chinese people die for (quite literally) and something Westerner's take for granted.
So, should we have 100% Freedom of Speech or should there be restrictions on what is allowed to be said?
If you answer for either, why and if you answer for the latter, then how far should it go?
If we have the freedom to say what we want when we want, we then run the risk of offending people needlessly, having some people incite hatred and extremism in public and give neo-Nazis, terrorists and other generally evil people the right to speak unchallenged.
On the other hand we might risk our societies becoming (more) Orwellian/Socialist if we start defining and regulating communication. Read Soviet/Chinese modern history and 1984 if your not sure what those adjectives mean.
