I think it was a mistake of the left to brainwash white kids to think of themselves as belonging to a group of evil oppressive colonizers - precisely because a few decades of that type of over-the-top racial "justice" schooling has led (inevitably, and even understandably) to the white nationalist backlash we're seeing today.
What should have happened was to stick with the individualist, civil rights notion that all men and women are created equal. Full stop.
Your complaint about the brainwashing is valid to a point, as no one should be raised having guilt for being born of a particular race/ethnicity, and in fact people should take pride in their heritage.
However, you do not explain why you think it matters whether a majority of the US remains of European stock, (by which I guess you mean not mixed race as well). And this is where your argument is transparently, well, racist. Because to explain that, you would probably need to denigrate other races.
I think you could make an argument that Europeans should stay a majority in Europe, on the basis that it is Europe. But America is not Europe, and never was. Europeans were a minority throughout the Americas when they showed up, and they will be a minority here again, and I don't see a big problem with that.
[edit] Just to add, there was nothing "sane" about the way Europeans conducted themselves either on the continent or here, especially in the decade prior to 1945. Also, prior to 1945, there was no general notion of "European", but rather many smaller nationalities. From 1941, it was a widely held idea that people of German descent for instance were a threat to America and should be deported. In the 19th century, a lot of people thought the same about the Irish, and you would have had to replace "European" with "English" in your statement to get some sort of nativist reaction.
