We are SLAVIC.
Serbia is CHRISTIAN. Serbias top two religions are Orthodox Christian and Roman Catholic.
So here's your proof. Anyone who says otherwise to either of these facts is LYING. Ive seen Hungarians, Croats and Albanians say otherwise to these facts. Likely an attempt to make themselves look good and us bad.
But only a major idiot would believe what they say, all they have to do is look it up and see that the Hungarians, Albanians and Croats are WRONG.:)
