As a researcher, Bulajić promoted high figures for the number of victims of the Jasenovac concentration camp. According to sociologist Jovan Byford, Bulajić belonged to a group of authors whose works supported the Serbian side against the Croatian side in a "war of words" which became propaganda war after the involvement of various state ministries. These authors depicted the "genocidal nature" of Croatian nationalism, as well as the role of the Catholic church in the genocide committed in WWII, while denying the existence of any form of anti-Semitism in Serbia.
