We still won't face what has been done to America, and so we cannot face what will need to be done to save America

I don't think it is a question of whether or not it's too late to save traditional America as we have known it, it is too late. The immigration act of 1965, which was a government sponsored mandate for open immigration, led by one of the degenerate Kennedy brothers, ended America as we knew it, and that is not counting the 10 to 30 million illegal aliens who have entered the country. And it's probably impossible to send them back. The same thing, more or less, happened to the Roman Empire.

But that is almost a secondary problem to the problem of assimilation, because distinctively different ethnic groups do not assimilate, only ethnically homogeneous groups "melt" together.

I don't think the Kennedy's and their modern liberal ilk were so much stupid as they were decadently beholden to those who gained, at least temporarily, from destroying the Northern European character, tone, and guiding beliefs of America. The old guard needed to be shunted aside by those who would not and could not assimilate with them.

But conservatives still won't face what has been done to America, and so they cannot face what will need to be done to save America. The reality points toward the political/cultural solution of the ethnopluralism hypothesis, often written about here. It is a conservative transformation---not revolution---that I see coming inevitably, which will bring about the more humane ethnopluralism of ethnostates, where different ethnic groups can politically and culturally conduct themselves the way they are, and the way they want to, in their own states within our Democratic Republic, perhaps with only a few amendments to the constitutional separation of powers and states. We will need to retain federalism and balance the states together because we need the geopolitical heft of a large nation to defend ourselves in the big world.

That is the sociobiological and political/cultural structure most in harmony with real human nature, which remains kin-centered, gender defined, heterosexual, marriage-making, ethnocentric, even xenophobic, with group-selection as the primary unit of successful selection, followed by individual selection. The decadent Kennedy types and not suicidal immigration polices can't change basic human nature, even if they have destroyed traditional America.
