What is wrong, after all, about insisting that only people who are predisposed to LIKE the United States are to be allowed to enter?
Those who consider the United States to be the center of evil in the world nave no business here anyway, if only for their own moral welfare - why would they want to visit such a den of inequity? But more than that, if they believe the United States to be unworthy of their respect and admiration, then they come here only as a concealed criminal, with malice aforethought directed at causing the collapse of all that is America. And this is indistinguishable from being an enemy agent.
And further, as a guest of the United States, it is expected that in no way shall they become a burden upon the people already here - that they come with some basic understanding of our language and customs, and they are able to pay their own way once here, without relying in any way upon the social network that, frankly, was established for the benefit of unfortunate citizens who have slipped through the cracks. And if these visitors come with the intent of working, bring some marketable skills, we absolutely don’t need to import any unskilled manual labor. Better the jobs go unfilled until they may be automated, than to create an underclass that shall never advance to any rung of the ladder.
What is wrong is obvious. Those who hate America will vote for democrats, which is why the party of communists wants legal and illegal immigrants who hate us and who hate our Constitution.
