Unless we set our house in order

Slate quotes:

“Unless we set our house in order, the doom will sooner or later overtake us all. And that would mean that the race obviously endowed with he greatest creative ability, the race which had achieved most in the past and which gave the richer promise for the future, had passed away, carrying with it to the grave those potencies upon which the realization of man’s highest hopes depends,” wrote Stoddard in his 1920 book The Rising Tide of Color Against White World-Supremacy.

I had never heard of that book, but it is freely online. It is filled with plain talk that is considered impolite today. It calls World War I the "White Civil War".

Here is what is says about California:

Our Pacific coast takes precisely the same attitude. Says Chester H. Rowell, a California writer: “There is no right way to solve a race problem except to stop it before it begins.... The Pacific coast is the frontier of the white man’s world, the culmination of the westward migration which is the white man’s whole history. It will remain the frontier so long as we regard it as such; no longer. ...

Says another Californian, Justice Burnett: “The Pacific States comprise an empire of vast potentialities and capable of supporting a population of many millions. Those now living there propose that it shall continue to be a home for them and their children, and that they shall not be overwhelmed and driven eastward by an ever-increasing yellow and brown flood.”[177]

All “economic” arguments are summarily put aside. “They say,” writes another Californian, “that our fruit-orchards, mines, and seed-farms cannot be worked without them (Oriental laborers). It were better that they never be developed than that our white laborers be degraded and driven from the soil. The same arguments were used a century and more ago to justify the importation of African labor.... As it is now, no self-respecting white laborer will work beside the Mongolian upon any terms. The proposition, whether we shall have white or yellow labor on the Pacific coast, must soon be settled, for we cannot have both. If the Mongolian is permitted to occupy the land, the white laborer from east of the Rockies will not come here — he will shun California as he would a pestilence. And who can blame him?”[178] ...

Fortunately, the majority of thinking Americans are to-day convinced that Oriental immigration must not be tolerated. Most of our leading men have so expressed themselves. For example, Woodrow Wilson, during his first presidential campaign, declared on May 3, 1912: “In the matter of Chinese and Japanese[Pg 287] coolie immigration, I stand for the national policy of exclusion. The whole question is one of assimilation of diverse races. We cannot make a homogeneous population of a people who do not blend with the Caucasian race. Their lower standard of living as laborers will crowd out the white agriculturist and is in other fields a most serious industrial menace. The success of free democratic institutions demands of our people education, intelligence, and patriotism, and the State should protect them against unjust and impossible competition. Remunerative labor is the basis of contentment. Democracy rests on the equality of the citizen. Oriental coolieism will give us another race-problem to solve and surely we have had our lesson.”[181]

Slate mentions this book with a claim that it has some similarity to Trump's message.

From Trump's Poland speech:

And if we don’t forget who are, we just can't be beaten. Americans will never forget. The nations of Europe will never forget. We are the fastest and the greatest community. There is nothing like our community of nations. The world has never known anything like our community of nations.

We write symphonies. We pursue innovation. We celebrate our ancient heroes, embrace our timeless traditions and customs, and always seek to explore and discover brand-new frontiers.

We reward brilliance. We strive for excellence, and cherish inspiring works of art that honor God. We treasure the rule of law and protect the right to free speech and free expression. (Applause.)

I guess the idea is that writing symphonies and pursuing innovation are things that white people do. Praising these things is just a sneaky way of expressing white identity politics. Or so is the theory. Likewise defending Western Civilization or free speech or American values will be considered pro-white, because mainly white people care about these things.

Obviously there is huge overlap between the creators of modern civilization and whites, Christians, English (and related language) speakers, etc. If the folks at Slate like to think of civilization as white culture, it is a first approximation.
