Nice strawman, and I even think you threw in some kind of retarded reverse slippery slope bullshit in there too. I never said they were all the same, I said this ridiculous concept of "illegal ideas" isn't specific to the third world, though like everything else their punishment is a hell of a lot worse.
You're like one of those douches who argues that since I think there's too much taxation I must think there should be 0 taxation, and that to raise any issues about how much we're taxed or how that tax money is spent means I must be for private roads and anarchy.
What should be illegal is speech which poses a threat of imminent danger or rises to the level of threats of bodily harm. Fraudulent statements should be illegal. Slander/libel (though with a fairly high bar of proof on behalf of the slandered person) should be illegal. Trafficking in child porn (actual, not virtual).
What _should not_ be illegal is easier to classify - basically any statement of opinion or support of an idea, regardless of how stupid the idea. Holocaust denial, sexism, racism, homophobia, even the ridiculous 99% vs 1% incitement should be legal unless they actually call for hangings and executions.
You want to know what's fucking facile? The argument that since we will always have government controls over something that we shouldn't criticize or debate the extent of those controls.
"Oh, well Jolly Fuck All. Since we will always have taxation, what's your problem with an 80% rate? I mean what the fuck kind of idiot doesn't know we will always have death and taxes?!".
