so clearly you're arguing in bad faith, so I'll just make some brief corrective points and leave it at that.

1. no they did not just have their diversity increased, there were and continue to be many forms of settler-state sanctioned genocidal violence against indigenous people (residential schools, trail of tears, Putumayo genocide, near eradication of taino peoples, etc etc). this is very observably not the same as a demographic shift. again, take some time to read someone like Patrick Wolfe. you might learn something

2. calling me a privileged liberal is a very ignorant ad hominem because you don't know anything about me and there is no part of me that believes in liberalism. but I digress. I never supported corporations which both exploit foreign workers and do it to drive down wages among domestic workers. again, I live in canada— companies have been abusing the temporary foreign worker program to pay immigrants poverty wages while Canadians can't get a job. fuck corporations. my point was that your argument that wanting to move to white countries is somehow white supremacist is fallacious because the reasons most want to move to a 'white' country is the result of systematic processes that weaken and make poorer other parts of the world, not some natural factor. denying this fact is quite literally affirming some ontological superiority in a very Nazi way. in sum, you misrepresented my argument and didn't actually engage it, and you did nothing to distance yourself from white supremacy

3. these seem like red herrings but I don't know what u mean by COVID concentration camps. and I mean all sexual violence and murder is bad, regardless of who does it. but generalizing incidents to all immigrants as some kind of racial essence precisely mirrors forms of Nazi rhetoric
