It isn't skin colour, it is culture. Having one's culture replaced by another. Every culture has fought against that, that is what fights against assimilation by minorities are about, why is it morally wrong when it is the majority feeling threatened?

Especially when it is forcefully encouraged by one's elites through mass illegal immigration, and with preferential hiring of non-whites, massive social programs directed towards those illegal immigrants, etc.

More gradual, controlled immigration that allowed for successful assimilation, as happened in the past, and programs that encouraged colour-blind hiring rather than preferential hiring by race, would do wonders to calm down the situation. There is little resentment of Asian immigrants for those reasons, they integrate well.

Why has there been little discussion that Trump's proposal is for a more Canadian-like model? Too embarrassing?
