This might not be exactly true (your statement). I mean even though you have freedom of speech you still can't legally say for example : "Kill the damn Jews !" or something like that, because you're incouraging a violation of someone else's rights (to live). By the same principle calling for a ban on speaking about piracy is incouraging a violation of someone else's rights (to free speech) and should therefor be a crime (not saying the two are equal in magnitude of course).
I believe that proving that someone is wrong/right about "Kill the damn Jews!" is less harmful that not letting them speak out their mind, and let the keep thinking that "Kill the damn Jews!" is "alright/wrong".
Avoiding the discussion is not healthy in anyway, even if the subject being censored is something illicit or illegal.
