Trump’s temporary ban on immigration from seven countries has raised lots of questions and, as usual in controversial situations, the various sides in the debate focus on different questions.
Trump and his team argue that such a ban is his legal right. The courts will decide whether that is true. The protesters and marchers care little about the legality and argue instead that the ban is neither moral nor wise. Both areas — morality and wisdom — are beyond the reach of Trump’s team. They cannot think in such terms.
Trump does throw up a bit of a smokescreen, of course, with his argument that the ban is necessary for American public safety. The thinness of this argument is shown by the simple fact that, while these seven countries may have potential terrorists trying to get into the US, several other countries — such as Egypt, Saudi Arabia, and Pakistan — have already been the source of terrorists.
And it is worth noting that America already has the most extensive immigrant vetting system in the world. Trump may tinker with it a bit but he will not be able to improve it significantly.
America, though never rid of racism prejudice, has for the most part prided itself on being the land of the free and the home of the brave. Trump would have us be the land of the restricted and home of the cowards.
