It should also depend on the context. A remark, which might be intended as a joke, can be quite offensive to a person yet another might see nothing wrong with it. Especially when people hardly know who the other person is, it's quite possible to come across as insulting or offensive due to cultural/social/religious context without really meaning to.
I can't wait for those specific situations to show themselves and watch and people try and insult people in the most round about way possible. But hell, that is fine, that will be clever and creative and fun for all. The "idiot" remarks tend to come from a level of person who can only think of a great insult such as 'idiot!'
I will say though, cultural, social, and religious context type humor that is directed at no specific person, but rather groups.. wouldn't that already be something not showing up here. Isn't that some kind of hate speech depending on the group?
Thinking of this thread in that way, would it be okay for someone to have some kind of Anti-Jew movement for Bitcoin on the forums protected by their free speech? Whatever it is people tend to think "free speech" is on a private forum anyways lol.
If hate speech does or does not work for groups, why or why not the same for individuals protection? Insulting directly is the ultimate hate speech.
Also it is retarded and is holding back any progressive discussion. I would love to hear someone argue this statement.
