Nationalism could be considered as a great love for ones own people. Or it could be seen as utter hatred towards any other people.
Racism is the same. It could be a preference for one's own race over other races, or it could be seen as a total antipathy towards other races.
Don't let your enemies define these terms for you. Let your nationalism and racism be based on love of your own kind. Love is a greater motivating factor than hate.
We don't need to hate our enemies, we only need to defeat them and secure our freedoms for us and our posterity.
Have you ever tried NOT hating jews and niggers?
I don't think about tarantulas or scorpions either.
