Why do people believe in 'White Nationalism' ?

Why do people believe in 'White Nationalism' ?

There must be as many answers to that question as there are people,
to answer that question.
Two identical answers don't make much sense:)

Because we reject utterly and completely, the jewish lie of multiculturalism, and equality of the races.
We know that Whites are superior, and the fact that we are villified, and maligned in the jewish media, thousands of times each day, proves this fact.
Any more questions?

White Nationalism = multiculturalism. Mixing individual ethnicities wipes out individual cultures of the white race.
