Mass Protest in the Netherlands by Farmers.

The genetic heritage of those people will change over time, that’s what you really mean. Europe is getting less white, I don’t care about that, only a bigot would care about it.

If Africa was becoming less Black, or Asia becoming less Asian I'm quite sure the narrative would be somewhat different, especially in the case of the former. This so called "diversity" stuff is almost entirely one way. IE it's White "christian" European cultures that are seemingly in such dire need of it. Cultures outside of that are apparently grand and certainly in no need of extra White "diversity".

There's a strong bias, even fetish of sorts around darker skin and on both sides too, though pretty much only among White European culture(and their colonies). Asians and Africans in their own neck of the woods not nearly so much and can have quite different positions that would make the Right On's toes curl. The Right see "Black" at the top of the tree of concerns, of "replacement" and all that guff and you're some sort of "traitor" for not pointing that out. The Right On see them at the top of the tree of added "value" and you're a "bigot" for pointing that out.

We already see this in Ireland, even over a much shorter period of time compared to the rest of "multicultural" Europe.. Of the inward migration to Ireland over the last twenty odd years the vast majority have been White Europeans in background, yet the Right and the Right On focus on the tiny minority of Black inward migration(under 2% last time I checked). Indeed the number of Ukrainians that have come into Ireland in the last four months are about the same number of Black Africans who have come here in twenty five years. We have Black History month, yet the Poles don't get a wet Tuesday in November and there are over three times the number of them.

And European(and IndoEuropean) is a collection of ethnicities with a shared history and genetic heritage, even down to the bones that goes back to the mesolithic, neolithic and agricultural revolution and beyond and even further back than that. If someone is a Native European they have archaic human admixture that is quite distinct from native African and Native Asian, who have their own mix going on. Those are roots going back over 40,000 years in all cases. A pathologist or archaeologist can look at a skull and make a remarkably accurate call on the once owner being African, Asian or European. Oh and ethnicities have indeed gone extinct. There aren't a lot of Picts knocking around today are there?

Culture is a defining part of ethnicity. You seem to be using enthnicity as a "race" marker. I don't use race as a definition, simply because it's a highly dubious one. I prefer populations based on shared genetic history, which roughly follows obvious "race" groupings. As for culture I am quite happy to say I'm culturally biased. I most certainly don't believe in what I see as the fashionable BS of cultural equivalence where there's an equal weighting for all and everyone gets a prize for showing up. That's not based on skin colour either. Look at Irish culture. 60 years ago Irish culture while there are positives to be found, was in so many ways inferior to Irish culture of today. Same "race". As for inward migration into Irish culture of today. I don't see it as particularly wise to import, or worse actively celebrate the importation of religious and conservative cultures that are as backward as, or moreso in some cases than ours of 60 years ago. The hope that somehow the same cultures will magically and organically absorb the positive changes of the host culture is a vain hope indeed and one that has proven to not be the case in other so called multicultural European nations. If anything, such positions harden over time.

And this diversity wasn't nor isn't inevitable. In Ireland it came about because of a perfect storm of a jus solis loophole and a major upswing in the economy of the late 90's. If neither had been present we wouldn't be nearly so "diverse" today. Add in a total couldn't organise a pissup in a brewery reaction by our authorities, mostly based on misguided charity and a need to be the best boy in the class looking for pats on the back for being so "progressive". One that continues down to today, where shortsighted moronic policies even in the face of homegrown moronic mismanagement are not making things any better.

On the other hand beyond this White European politic, Japan a non European solidly first world nation that has had economic booms didn't become "diverse" as some sort of inevitablity. Neither has China for that matter. They have actively made steps to make sure it hasn't become one and the "natives" are most certainly the drivers of those societies. Oh they both have certainly absorbed a lot from non local cultures, majority European cultures, but they didn't absorb actual people from those cultures. That goes for pretty much all East Asian nations and cultures. Similar goes for many Eastern European nations who aren't nearly so diverse as their Western counterparts and have actively gone against this trend.

Most of this this "diversity is inevitable" stuff comes from the same source as your noted importation of European-American culture. It was "inevitable" there simply because it's an ex European colony founded and sustained for generations on immigration either willingly, semi willingly in steerage, or in the hulls of slave ships. They are stuck with it, buggered it up and did so even more than human nature would bugger it up anyway and have since the 1950's and 60's tried to keep a lid on the situation they found themselves in, and spun this "melting pot" and "diversity is great" stuff. And fifty plus years since MLK had a dream much of it is still mired in dreamland. The same stuff has been taken up by those European nations who by virtue of their overseas colonies also became stuck with it. Ireland doesn't fit in either category. Neither does a nation like Sweden.

And you're most certainly more under the banner of the Right On. And that's fine, but it's a tad disingenuous to suggest you're not. I'm more old style Liberal, even quite lefty liberal, but would be considered by some as right wing for questioning the IMHO failed political experiment of multiculturalism and diversity. And as for being colour blind, unfortunately history, current and past in every single case of nations struggling with diversity quite clearly demonstrates that the majority aren't colour blind and not just the palefaces and this increases divisions.
