You need to relax a little. Not every person with an accent wants to kill you.
You think...most American’s can’t differentiate between a Maine, New Yorker, Southern, Hispanic accent....from a Middle Eastern accent???
Of course here, most consider their birth certificate their cc license so enter at your own risk.
If they are muslim with an Arabic accent (of Middle Eastern origin), the chances are they will sooner or later.
The highest calling for any muslim is to follow in the footsteps of their prophet. Mohammad personally beheaded 300-400 Jewish captives after a battle.
Relaxing is how the US got in this situation in the first place. Relaxing is how Mohammad and his disciples managed to destroy classical western civilization, classical Christianity, and turned North Africa from the world’s grain basket into a semi-arid desert.
You relax, keep believing the taqiyya ...
