Nazism

Explanation:

The Nazism is often viewed as an extreme form of patriotism, and rightly so. The Nazism is not the typical type of patriotism. The patriotism is good, as it is focused about the traditions, culture, heritage of the people from certain country or area. The Nazism on the other hand, is all that, but it also promotes the ideology that the people of that particular ethnic group are superior to all other groups. Often that goes in a manner where the other ethnic groups are portrayed as not worthy of living, and that they are the ones that cause all the problems in the nation, and are stopping the progress of it. That unfortunately usually ends up with military conflict and genocide.
