I don't want certain cultural values to change in my community. some of these cultural values are very important for my safety. if my community gets an influx of outsiders and it happens too fast for assimilation to take place, the culture may change in ways that are harmful to me.
I can tell myself that it's not my race that matters, it's my cultural values. but I don't see everyone else in the world doing that. most cultures will use their race as a team to a greater degree than mine. a white nationalist is just a person who chooses to do what he sees almost everyone else doing.
how else are we supposed to prevent assimilation from being bypassed, so that our cultural values will not be changed by outsiders in harmful ways?
