Majority of Serbs are actually Orthodox Christians and very serious about it. Only about 4% of Serbia is muslims. I think you might be thinking about this Kosovo dispute, where Kosovo is the region that historically belongs to Serbia that has been occupied by Albanian muslims and has segregated from Serbia under protection from NATO. Kosovo is over 90% muslim.
Most millennials and above Croatian and Serbian nationalists are trying to get away from division that war in 90s caused for us and we try to find a way to work together. Both of us see what has happened in the West, and don't want the same to happen to us. We can put our differences aside if it means working against getting our continues filled with nigger and indians.
I simplified for Theo to be able to understand. ;)
He might work it out eventually.
