Anti-Serb pro-Jihadist posters are like cockroaches, even the nicest forums have some.
Anti-Serb ? Yes, in their present state.
Serbia is about to vote in a government that will try to preserve and restore the Communist state and ally itself with Russian imperialists. To say that they are the odd men out in the post-Cold War Eastern Europe would be to put it mildly.
Pro-jihadist ? No. But the US and the decent parts of the world have enemies other than jidahists. The Serbs seem to want to join them.
