Do not be misled into accepting the narrative that most Europeans want to have their homelands over-populated with incongruous new arrivals. Most Europeans are simply intimidated by their own pseudo-intellectual betrayers' version of the "politically correct" fantasy that people are interchangeable--the same idiocy that drives the Clintons, Obamas and the like.
There, as here, are two groups that feed off that fantasy, and correspondingly manage to keep most other folk silent--intimidated and silent. One group are those business interests, which put immediate profit ahead of patriotism.
The other group are the compulsion driven neurotics, who for one reason or another, simply cannot tolerate the realization that peoples, as individuals, differ;--that we are all unique, and should be respected for our particular unique qualities--not artificially mixed up in an effort to validate a Leftist/humanist pipe dream.
Because Donald Trump has defied the "politically correct" conventions, that were strangling analysis of real problems in Western countries; because of his rise in doing just that, there is now more hope for a Western reawakening than there has been in decades.
The ultimate issue, both here and in Europe, is whether we--the people of each nation--dare again to be unique; dare, again, to honor our heritages and the noble figures in our respective histories, who helped to develop the impressive cultures of our respective nations. Those cultures, now being trashed by crack-pots), reflect the respective but cumulative struggles of those nations, over the past twelve hundred or so years.
Of course it's irrational, it is contrary to all historical evidence, and belief in this power of the state resides principally in those for whom that power is an article of faith, not rational conviction. And they are as dangerous and difficult to persuade otherwise as all cultists are.
