Oh!! that explains it. Any links to back up why they are so nice?
you should eventually trust to Serbian about it. For us, its religious question. There was debate on TV regarding SLAVA that Serbians still massively celebrate (back in past universal Slavic custom) and experts agree that love for ancestor that was never seen (but we know for sure that he existed), stimulates altruistic feelings in Serbs. Sure, parallel with it, celebrating SLAVA, Serbians follow imaginary picture of their ancestors and therefore they don`t like to mix racially (picture of, for example, Black descendants doesn`t fit in image about White ancestors and one tend to preserve image of ancestral line). Yes, yes, SLAVA is genuine remain of old Slavic faith in Serbian spirituality. Thanks to it we Serbs were able to survive Turkish and all other invasions (including this recent NATO, EU and Islamic league) and at the same time to preserve our humanity. That is why Serbians and Belgrade were able to be founding country of Non-Aligned countries movement and at the same time to be spiritual engine of Slavic civilization.
Anybody who walks in my door in Poland is my guest.
In old Slavic faith, due to spirituality deeply influenced by ancestral cult, first thought of ancients when they received unknown guest was that guest eventually represent their own oldest ancestor or deity in connection to ancestral cult. If guest was wounded or limp, he was regularly considered connected to Dadźbóg (in Polish), Dabog (in Serbian), a limp God- one of the major gods of Slavic mythology, a solar deity, a cultural hero and personification of rain and fertility and also oldest ancestor, God of this world and underworld. Ancient Serbs thought that it was God Dabog that gave birth to all Slavs (ie Sarmatians).
