I would have to disagree. I’ve lived in Alabama most of my life and it’s always been referred to here as “Bloody Sunday” here. I was 10 years old at the time of the march and I remember the “old” south very well. The KKK came to my town one time that I can remember and had a big cross burning at the local airport. My dad loaded us all in the car with mom’s protest and drove us by to see it. I was truly frightened by what I saw and will always remember it. Much has changed in my state since those days. I’d put our race relations up against any state these days (not what you hear in the news about Alabama but the true state of affairs)...but that’s just my opinion of course.
I will bow to your knowledge, Bamabelle! I just never heard it applied to this event.
