There are few things more natural than people from different places and cultures being suspicious of one another. Human beings are tribal by nature, and tribes have always been exclusive.
As human societies grew larger, the “tribe” to which we are loyal has expanded, and the characteristics we use to identify who belongs to it can shift beyond mere proximity and familiarity. We can even have allegiances to different tribes at the same time. Texans tend to see themselves as members of their local community, Texas, the “tribe” of their favorite sports teams, and as Americans. Sometimes the tribal allegiances overlap, and sometimes not.
I guarantee you that Floridians and Texans worry about the influx of people from Blue states changing their politics, so imagine what happens when a person from a different country, culture, religion, and who behaves very differently from you, horns in and demands that you change for their benefit.
And, by the way, demands that you pick up the tab for their new lives.
