This is very true. Until the early-mid 90s Muslims who came to this country often acted very un-Muslim. It was a relief to them to get away from the suffocation back home. But then the Imams trickled and (with them) the enforcers. Now even the West isn’t a safe have from Islam.
At the end of WWII, peace with Japan was in the offering and Halsey had been advised to show a friendly face. When Bill Halsey was asked what he would do if attacked by Japanese airplanes, he replied “shoot them down in a friendly manner”.
From memory, but it’s close.
