There were almost no Jews in Kosovo when Serbia was in power and there are almost no Jews in Kosovo now that Kosovars are in power.
There weren't that many to begin with, and most of them left for Israel when the Balkan wars broke out.
As for the Serbs and Roma, all too often they were subjected to ethnically motivated attacks, pogroms, and at the least harassement or discrimination.
In the case of the Serbs, I'm sure the harassment and discrimination charges are absolutely true. After all, the shoe was on the other foot just months ago. No people in the Balkans seems able to let bygones be bygones.
I've heard no credible reports of any pogroms.
Ignoring the destruction of all of those Christian Churches, eh?
Or were you cheering them on with this crowd?
