No they are Muslim
This is Salafiste extremism, you can keep it for yourself, it is not for you to declare takfir.
By “our” I meant “my general area”, not, “all of the US”. But I’ll go with what little nemo said.
But I’m seeing that /your/ understanding of Christian cultural context seems a bit limited. Clearly /I/ made a mistake using Christian terms to describe muslim activities, because that seems to have contributed to the misunderstanding.
And I guess, sort of un-American as well. The Muradiye Complex (circa 1450), included baths, hospice, and a school.
