I addressed this question: "Or will that leave them as individualists in a country dominated by inter-group competition, as current polls suggest?"
Of course this is not guaranteed - once Whites are a minority (in the US, not just globally), other races in the US may also turn away from in-group preference, and the culture might turn away from harping on white privilege all the time. It's just that that hasn't happened yet.
I agree this is interesting to watch. Minorities have more voice in the culture as the demographics change, and some in the majority want to push back. Identify politics is toxic, no matter where it comes from. The media and politicians don't seem to be helping.
That said, if immigration was becoming a major issue then you would see shifts in the electorate backing say the People’s Party that performed dismally in the last federal election.
Could that change? Sure. But it would have to be via the Conservatives and that’s a risky policy shift for them to make.
I also think you can’t group Latinos as a voting bloc that swings one way on party or policy. Sure Latinos in Nevada lean blue and are more liberal but in Florida they are conservative and are voting Republican.
Overall though I disagree with the framing. Why is a white minority a bad thing? Canada’s response to such demographic shifts is much more measured. We’re building a country together.
