You know what, I lived in Alabama when all the marches and protests started. It was mostly outside groups stirring up trouble over staged events, and about problems that didn't exist in most cases.
Everywhere in the country the roadsides had outside BBQ tents set up and almost all of them owned and run by blacks. There would be dozens of picnic tables under the open sided tents and about an equal number of blacks and whites eating together. Everybody sat at whatever table had an open spot. Nobody cared where anyone sat and everyone got along fine.
Before all the riots and protests, nobody knew that we couldn't get along or had to eat in seperate places. It's a good thing the liberal commies came down and let us know how much we hated each other, we would have never known.
Well, I was in Mississippi and Alabama in the early 1970s and racism was VERY strong then. Yes, there were settings where groups could mingle-—music, in particular. But one my pastor friends, a nationally known black minister, STILL couldn’t preach in various churches down there until about the 1980s. So, no, it wasn’t all “outside agitators.” The people I knew and played with were born and raised in Alabama and Mississippi.
