I don't declare support for either balkan faction directly. But maybe I can clarify a bit with some history.
Fact : Serbian churches are being torched in Kosovo. Or have been, very recently, since we bombed Serbia, and allowed Albanians to set up their de-facto state.
Fact : During WWII, there were serious collaborators on all sides. More notorious ones were Muslim - there was a Nazi SS muslim brigade and Croatian Ustashe, and some Serbian 5th column elements.
What the bosnians think of as 'Nazi supporting animals' were Chetniks, a Royalist/Loyalist faction, which fought for restoration of the king/monarchy against the communist partisans (led by communists, encompassing Croats, Serbs and Muslims) and the Nazis. They were neither nazi supporting, nor animals. At least no more so than the rest. It's just that Bosnian history books don't agree with the ones you'd read in the US, for example.
Since WWII everyone had their grievances, and those were ruthlessly supressed by the communist regime. When the communism collapsed, all the nationalistic elements came to power by stirring old grievances. And then everyone made new ones.
The reality at this time (important, because we live in present day as opposed to some people who live in the past) is that the Bosnian muslims that existed there in the 80s and 90s (relatively secular, normal , european people) got very much radicalized after the Bosnian war. Turning to Saudis for help since there was noone else does that. Also most of the intelligencia on all sides, Croatian, Serbian, and Muslim, left Bosnia. What is left now is only a shadow of the former society, and, again, a fertile ground for extremist points of view.
While everyone and noone was to blame for what happened in the past (I'm chalking it up to post-cold war geopolitics), the truth is that Bosnia *today* is bordering on a nightmarish terrorist scenario. All caucasian, ethnic Serbs forcibly converted during 800 years of Ottoman rule, that are virtually indistinguishable from other europeans, are being indoctrinated in Saudi founded/funded mosques. Do the math.
Is it all Bosnian Muslims, or is it a faction that has become radicalized? As Europeans, they are not Wahabbist en masse, are they?
The peace keepers are still there and we do not hear reports of terror, roadside bombs or attacks. It can't be all bad, can it?
