The US House of Representatives last week approved legislation that would stall America's program for accepting refugees, demanding stricter security provisions on the screening of Iraqi and Syrian refugees. To date, 32 American governors (out of 50) have issued statements saying they would bar Syrian refugees from settling in their states, citing risk of violent extremism, fears fanned by the recent Paris terror events. (Symbolic, as they lack rights to do so.)
The US vetting process for Middle Eastern refugees is perhaps the most stringent on the planet, suggesting that "security" isn't the only fuel powering the anti-refugee movement. See some of the hurdles a refugee must pass and learn how irrational it is to fear them.
