Yeah and in North Korea I can't call Kim Jong Un a fat piece of shit, but I guess that's just a reasonable limit to North Korea's freedom of speech.
> In a German cinema you can't shout "The holocaust never happened"
This is a legitimate example of why Germany does not have freedom of speech. Regardless of how verifiable the Holocaust is or how offensive it is to deny that it happened, disagreeing with the government's version of history should not be a crime in a free society.
> In a US cinema you can't shout "Fire" if there is no fire
A fraudulent statement designed to disrupt society. You don't get arrested because what you said is untrue, you get arrested because you're legitimately trying to hurt people by causing a stampede and desensitizing them to fire warnings.
>"Kill all muslims"
A specific incitement of violence.
> "I just got a national security letter"
I don't like that this is illegal either, but it's a far cry from making it illegal to express certain opinions. And at least there's a fair amount of disagreement within the US as to whether it should be illegal, different jurisdictions have taken either side of this issue.
