That's true, but most of the Croatians that did not support the Nazis were Communists loyal to Tito.
That's false. Those croatians, bosnian muslims (who identified themselves as "Serbs of Mahometan religion") and other minorities who diden't support the Nazis were loyal to General Draza Mihailovich's Chetniks. Tito's communists collaborated with oustachis and their prime enemies were Draza Mihailovich's Chetniks. Unfortunately, the only one who have studied archives of all forces in presence in yugoslawia during WW2, which are mostly held in Belgrade, Serbia, doesn't have the means to translate it in other languages than Serbian.
So let me at least show you a shorter edition of the study:
Translated title: "Collaboration of (Tito's) partisans wih Germans, Oustachis and albanians"
on the bottom of the following link, my fellow Serbs who have time can try to translate some pages in english, especially there is a copy of a pre-WW2 banned official newspaper of the Communist Party of jugoslawia where they claim that: "The Communist Party of Yougoslavia salutes the Oustachi movement"

"Fights of the (Draza Mihailovich's) Chetniks against Germans and Oustachis" book 1 and 2

Not only Albanian, but also croatian, macedonian, montenegrin, bosnian, etc... All those who used to be a part of the communist regime of jugoslawia, and inherited a puppet "independant and sovereign" state in the 1990's.
