If Hamilton County is anything like Berlin, Germany, they’re probably converts from whatever the dominant ethnicity is, and they simply don’t look/dress like “traditional” Muslims.
There’s tons of them in Berlin....you would never know they were Muslims if you didn’t see them entering or existing a mosque. Very few even have a beard; they’re mostly clean-shaved. In the case of Berlin, I’m talking ethnic Germans, of course.
Hamilton Co has about 10,000 people and 5 billion trees. I don’t know where they would be. It’s rural redneck America.
