Should whites fear takeovers by Mexicans and other races of non european heritages?

Why shouyld we hav eto accept thier cultures and degrade our roots? It seems as if you should hide your pride at being white. I say that's wrong since many advances have originated in my culture. That's not demeaning any other but I want to be able to speak freely and be just as proud as some native ritual dancer etc., isnt that fair?
