If that is what interests you, spend a second. Look it up. And then post what you find.
I posted the first known Muslim in America. 1528 is long before the U.S. Was founded. I am pretty confident the next one was here before 2001.
It would be very interesting to review the history of Muslims in the US after Jefferson and I will do that. I would think there were Muslims in the country before 2001. Farrakhan comes to mind. However, the immigration of Muslims into the US in recent years appears way increased disproportionately as does immigration of persons from south of the US mainland borders. Our, at least for me, European forefathers appear to becoming nonentities in US society. I can remember when there were quotas from any direction. Now it seems to me that there are no quotas for certain immigrants.
