World view can encompass a pretty huge spectrum of ideas. You can objectively define some world views as superior to others, such as political world views; fascism, capitalism, democracy, communism etc.
Wars between religious world views don't site any real world benefits, its one set of scripture and beliefs against another. You can compare fascism to democracy and make a judgement with logic. Try making a decision between religions like Catholics vs Protestants in the same way without having a personal bias rather than a logical bias
