Racism is much more alive and well than undoubtedly most Republicans would admit. A staunch Republican at another website told me that racism is pretty much gone in Tennessee where he lives, and a friend of mine who lives there just about died laughing when I told him that.
Even here in the "blue states" it's bad. We've lived in the same house for 41 years now, and there are three restaurants walking distance from our place that in all these years have never hired a single black person even though there's a sizeable minority of them here. My wife waitressed at one of them, and she said that if a black came in to apply, they would chuck the application in the garbage as soon as they left.
If you've ever had the "pleasure" of listening to Limbaugh, he's as racist as the day is long. So, why don't these Republicans turn on him and tell him to shut up? Well, I do believe we well know the answer to that question.
Most of my friends and close relatives are Republicans, and you might think I'm exaggerating, but every single one of them is racist. I know this because we do talk, and they pretty much admit it directly or indirectly, but if a stranger was talking with them, they'd not likely know it. And racism works both ways as there are some blacks that are just as racists as some whites, and I have run into that as well.
It's an unfortunate reality.
