You cannot point to those from countries where terrorists are dominant without pointing at our veterans. You think we should fear refugees from such countries as Iraq, Iran and Syria? Look at the mass shootings in the U.S. More than a third of the perpetrators of the worst mass shootings since 1984 have military backgrounds.
So, one could argue that we should be just as cautious of bringing our own military back as we are about bringing refugees in from the war-torn countries.
Of course, let our veterans come home. No one even questions that. It is the right thing to do, even if they, as a lot, are more prone to committing mass murders than the average person.
But, also let the refugees come. Yes, there does exist the chance of a terrorist slipping in among them. But, don't judge the bunch by the few. Just as all veterans are not mass murderers, so all refugees are not all terrorists.
