I would assume that those who have little dealing with international business, tourism, generating and strengthening the global competitiveness of our country abroad through participation in fast-paced, dynamnic worldwide business, so we can beat the pants off our economic rivals and create even more jobs in the USA, will particularly "get it". I agree, there are ways to screen out dastardly islamofascist terrorists, but sometimes the US does does stupid, rash, things across the board as an overreaction, like the whole "kids on milk cartons" fad sweeping the US that actually ended up panicking US kids wholesale. Often we cut off our nose despite just popping a zit on it. This, IMHO, will help further the decline of the US and it's slow, economic self-strangulation, while buttressing other places to become financial centers of the world.
While I am of course strongly against illegal aliens, and also legal immigration if it goes overboard, I am not against legal travel for legitimate business interests for citizens of foreign ally countries nor am I for its slow, bureaucratic asphyxiation by know-nothing, clueless government wonks in the Beltway.
