You don't even have to go out of town. I was setting up for a trade show at the GWCC (Georgia World Congress Center)... way in the back of the lower level. My seedy hotel was just a few blocks from the booth location, about half the distance you'd travel if you went out the front door. So I went out a back door (which locks behind you, preventing re-entry), crossed some railroad tracks and climbed a fence... and traversed those few blocks in utter terror. Worst neighborhood I ever walked through after dark!
The Southwest side of ATL has an extremely high crime rate. Perhaps that's where you ended up. A home health nurse that I worked with about 20 years ago, was threatened by a black male with a gun once when she was trying to visit a patient. The guy came up to her car, brandished his gun and said, "What's the honkey bitch doing in this neighborhood"? Needless to say, she was quite upset when she got back to the office, but at least she wasn't harmed. We had to discharge the patient for safety reasons.
Most white people know to stay away from Southwest ATL. Actually, most people know to stay away from that area. I feel for the ones that can't leave.
But, if you ever visit Little Five Points, you'll think you've gone back in time and are in The Village in New York, as it was in the 60s. I've heard it's been gentrified now, and it's lost its charm, but I haven't been up there in years. The last time I visited the city, an old white woman stopped, glared at us, and then said. "Damn tourists." Assholes are everywhere and they come in all shades of skin. I guess we must have looked like we came from New Jersey. New Yorkers have always thought they were better than people from NJ. That river makes all the difference in the world.
Oh wait. What were we talking about? Trump supporters. Yes. They have some in New York City too. They're a minority, but they exist. My sister lives in a very wealthy suburban, all white town in New Jersey and Trump supporters abound there. I imagine they like their tax breaks.
