I mean, it not like we had Quacker colonies, Pennsylvania Dutch, Amish, Protestant, Catholic, Jewish, Muslim, and the various native groups at our founding, and who have been living and mingling with each other for 250+ years.
Firstly, I'm not aware of any Muslim population of the US or in the colonial period enough to be called a "community" until well into the 20th century. There may have been random Muslims here or there, but for the most part the early US was drawn from three main populations: Northern European (Specifically Anglo, German, French, Dutch, Scottish, and Irish, and for those that like to lump all those together as "white" within the period those were all seen as distinct ethnicities that had never before really lived together under one government), Western African (Mainly from the southern coast of West Africa due to the slave trade), and American Indians (there were tribes on the East Coast that fully integrated and effectively disappeared, esp. in the Mid-Atlantic region where conflicts involving the natives were often more complicated than Settler vs Indian*), and of these three by far the largest single group was the Northern European contingent.

* Hilarious point of historical racism... in the mid to late 19th century when "blood purity" became a Big Deal with things like the "one drop" rule, they actually had to revise where in the racial hierarchy American Indians sat in regards to "whiteness"... because you see many of the First Families of Virginia (the very wealthy and powerful elite families... you would recognize some of the names like Custis, Washington, and Lee, to name a few of the most famous) like to claim decent from Pocahontas... and if they actually WERE (they usually weren't, but many of them DID have some Native American ancestry as there WAS cross marriage in early Virginia) that would have made them not legally "white" because they would have had to much American Indian blood.
