So one of the gotcha points the left uses to justify multi-culturalism is that America (or Canada or Australia,etc.) was not originally a white country. There were indigenous peoples whom we displaced. Also in the case of America, we had the simultaneous arrival of large amounts of slaves.

I find that while one can argue that the cultural & ethnic fabric of the USA was overwhelmingly European from the founding, and maintained that status until well into the 20th century...it's not the most effective strategy. It puts us on the back-foot.

Far better to own up to the fact that we were settlers, stole the land from the barbarous natives, and then actually made a nation out of it.

Then, point to Israel as a precedent. If jews from all corners of the world, removed from Israel for two millenia can come together and form an ethno-state (while displacing the palestinians that have been there continuously far longer), then why can't we do it as well?

They have border walls, and tight immigration laws. Any sort of insurrection from the native Palestinians gets violently put down. All in all, it works pretty well.

And if the lefty you're arguing with claims those policies are controversial, tell him that only anti-semites say such things.
