Damn, but aren't such words a kind of death threat? so these posts should be deleted.
The way mods here seem to interpret the rules, only direct threats at a specific user would result in a ban, and even that's not always enforced. Saying that someone should be killed (but not directly saying "I'll kill you"), or that an entire nation should be exterminated is not considered a specific death threat... despite potentially breaking the law in some or many jurisdictions.
I have was consulted with theymos on this issue. I posted the results of this consultation in my post
here. It doesn't have to be about a user on the forum. Prohibiting specific calls for violence on the forum also applies to anyone outside the forum or any nation.
