LAS CRUCES, N.M. — The mother and daughter arrived just before 8 a.m., unpacking the table and folding chairs from the back of a white minivan. It was a chilly 43 degrees, and the sun cast long shadows between the farmers market stalls and the funnel cake truck, the smell of grilled meat and wood smoke hovering. Sureyya Hussain carefully laid out the Korans. Soon, the curious passersby began to approach with their questions, their comments and their concerns.
