Those have been my thoughts exactly. Sadly, our society is falling apart.
Maybe multi-racial / multi-ethnic societies are simply not viable in the long run... unless held together by sufficient brute force (like Titos Yugoslavia, and when the strongman dies, they disintegrate in a bloody civil war).
We are not allowed to consider any alternatives to the current state.
We are not a nation in any blood and soil sense. Such ideas are marginalized.
Neither we are a nation of disparate people held together by a strong common faith or a strong, assertive common culture.
Things fall apart, the center cannot hold...
