Hrvatski, Jtf has always supported the Serbs. This is not the place to wish for the destruction of their churches.
Judaism has always taught the destruction of idolatry, as Deuteronomy 12:2-3 states:
"You shall utterly destroy from all the places where the nations, that you shall possess, worshipped their gods, upon the lofty mountains and upon the hills, and under every lush tree. And you shall tear down their altars, smash their monuments, burn their asherim with fire, cut down the graven images of their gods, and destroy their name from that place."
If your heroic Serb doesn't want a Torah lesson, tell him to leave me alone.
