Forget race or ethnicity then. It isn't their race that must be profiled, but the violent worldview to which they've subscribed. It's called Islam.
Let's put it this way. If there was an organization that held Nazi beliefs and actually had collaborated with the Nazis in WWII that was discovered to be committing mass murder and had several members in the United States how would you react? What if that group had actually attacked the U.S. and killed nearly 3,000 people? What if that group was responsible for more mass murder worldwide than the number of Jews exterminated by the Nazis in WWII? What if the members of that group had a document that outlined the groups beliefs and that document included a call for endless violence against anyone opposed to them. And that document, in fact, detailed a strategy for world domination wherein everyone must join their group or lives as slaves or be exterminated. What if that group was violently anti-Semitic? What if members of that group kept kidnapping innocent people and then video taping themselves cutting their heads off? Would you want to know who the members of that group are within the United States? Would you want strong measures to be taken to deal with that group? If you permitted that group to continue existing (for whatever insane reason) what reasonable measures should be taken to ensure that the group is not engaging in murderous conspiracies as they had so many times before?
You know what group I'm talking about. I don't care if their worldview is a religion or not. If the Nazis called their worldview a "religion" should we have just let them alone? Islam openly seeks world domination. Islam insists that you and your family either convert, or become a slave (a Dhimmi) to them, or be exterminated. Unchecked, it is only a matter of time until you and your family will have to make that choice - join, live as a slave, or have your throats cut. Islam is spreading throughout the globe with over 7 million members of that group in the United States alone. They don't get a pass just because they're considered to be a religion. Given their stated goal and the historical record they should be treated accordingly.
did you see the picture of the ordinary looking mom holding her baby? She could be any mom anywhere in the world boarding a plane
it was her intention to have explosives in the baby's bottle and kill her, the baby, and everyone on the plane
if you think we can determine in advance who is willing to murder us us, then you can dream on, or you don't fly. which is it?
