How do you think countries vet their own people? Using the same techniques the US uses to vet people seeking to come here. Frankly I trust our vetting more than any other nation to do it. Here is a good summary of how we do the vetting. http://www.heritage.org/immigration/commentary/how-the-refugee-vetting-process-works
I am dumping on repubs for not adopting because they are the ones that insist all women give birth when they become pregnant - and I am talking about official party platform here. From what I can find alone, political persuasion does not seem to correlate to adoption. And by the way, when I ask the government do something it is my money as well. So the idea I am asking everyone else to pay for it is not correct. The while idea of a having a civic society is that we pool our money via taxes to accomplish things we could not do individually. That process means sometimes one's money is used in ways one does not support.
