I think what is important here is that the seven countries that are listed for this travel ban are terrorist states. If we hearken back to the headlines about ISIS training camps, American's that traveled to those sites and then returned home to carry out an act of terror, we may understand why this ban is vital to national security. And of course personal security.
Islam is a political ideology. Al Qaida has said that Islam, not Al Qaida and terrorist Muslims but Islam the ideology itself, is at war with America.
When there are over 1 billion Muslims affiliated with Islam, that makes the so called minority that are extremists, terrorists, ranking in the millions.
It is a privilege to enter into a country not a right.
All the 7 countries on the ban list are identified as terrorist states. Would we rather be safe from terrorists, or American traitors who leave America, go to ISIS training camps, return to America and then commit an act of terrorism?
OR would we rather insure our national security because we the people don't tolerate having our heads cut off by a lone wolf psychotic Muslim in the name of Allah! Because Political Correctness somehow won and that let that evil one into the country in the first place!
When a terrorist religion tells you it hates you and wants you dead believe them!
