Hi, SalaTar. Welcome to techIMO.

This is a problem all over, and it is a problem of fear and poor education. If people teach their kids to fear and hate on the basis of some thin prejudice, they're gonna do so until someone teaches them otherwise. Unfortunately, some folks will only learn the hard way, and many never learn.
I used to live in the "bible belt" myself. I don't anymore. But it doesn't really matter. I've lived in nine different states, and twenty different towns, from coast to coast and border to border.
You see this problem everywhere: little people with little frightened minds who must do something; but they can't think of something intelligent to do, and end up doing something hateful.
I have "Caller ID" on my home phone, and I don't answer strange calls at all. After all, my phone is for my convenience, not someone elses.
