Some days Ryan seems to be coming around to reality, some days he seems still to be embracing the rationalized notions of the most myopic of Corporate management. Based on over six decades of fighting the Internationalist efforts to subvert the Federal Republic achieved by Washington, Jefferson, Franklin, Madison, etc., I would make a suggestion:
We need to spend far less time speculating on the motives of those who ought to know better, but seem to endlessly rally to the patent fallacy that people are interchangeable--and hence it does not matter who comes here. Ryan may be devious, or just confused. But the reality is that a non-discriminatory immigration policy simply ignores the reality of human existence--we are all different. And if Ryan or your next door neighbor actually believes that it does not matter, whom we let in, they embrace a ridiculous fantasy.
More to the point, not only does an immigration policy which does not differentiate between candidates for admission, not protect the unique character of our institutions, founded by specific people with specific priorities; it insults the significance of the cultural pursuits and achievements of every other social culture/or ethnicity of every achieving people on the planet. In answer to the fantasy/egalitarian world of the American Left: Yes, Americans did build it, just as Mexicans built what they have--both the good & bad.
In short, the answer to confused, egalitarian fantasy "let's pretend," is mutual respect, coupled with a recognition of every people's right to build a heritage step by step, generation by generation, that reflects that people's right to prioritize what is most important to them.
Immigration worked best, when we drew people who came here because the unique culture appealed to the immigrants own unique personalities. In recent mob scenes, clearly hostile to our heritage, we can see how truly different are many of the more recent arrivals. The point is irrefutable.
Sociology 101: Some cultures are incompatible. In scores of countries the treatment of women, for example, is contrary to ours.
