>> I could give you a very simple example of cultural similarity across Europe. Religion. Pretty much the majority of European countries are Christians. >> 72% of Europeans are Christians. There are no "Christians" in Europe. You actually have Catholics, Protestants, Orthodoxs and a bunch of others. And those guys have been killing each other for very long time. The "Christianity-Version" of each region is actually a very fundamental property explaining those many differences (political parties, welfare systems, work ethics etc.) in Europe (which you claim don't exist).
