I like the Kanye example and relating it to power. Should free speech for power be limited but opinion not? How can one tell the difference?

Nyann: For the "moral" standing, corruption is found everywhere. Those in power are usually corrupt, and they set the countries general "moral" stand. How does this solve problems concerning freedom of speech when they could limit it to things they consider moral?

pinheads: Why should someone's opinion be limited? How does speaking about an idea harm others? If you are not allowed, in the privacy of your own home, to discuss ideas about Fascism, Nazism, or any other idea considered "bad" or "evil", it raises several problems.
How will this be monitored?
What decides where the line is drawn? Is theocracy off limits? Anarchy?

Limiting opinions is the same as limiting speech. Most speech is protected because it's an opinion, political or otherwise.
