White nationalism is forever tainted because of racism. Whites are not in danger of "disappearing" anywhere but USA over time, and that seems to be what
most freak out about. However since whites are largely in power...everywhere...nobody really feels bad for them.
History has show us that White Nationalism quickly turns to some sorta hate machine simply because they have the resources to oppress in order to secure
power. Multiculturalism DOES have a pervasive effect that will push the curve closer to brown in any place where mixing takes place.
Add to that the hate for anyone black, brown, and inbetween...White Nationalism

It's kinda doomed. Don't know how long it will take, but they kinda
have an idea.
P.S. look at the second video and the sign "How come diversity only applies to whites?" or some shyt. They don't understand just how much poorer people of every other race are in comparison to whites. Others come in...they try to carve a living into the dominant society somehow(usually.)
Whites come in? They change the nature of the culture, usually for profit. Who loses? Everybody without money. White folks don't seem to understand the inherent advantages they hold, even the poorer ones.
