You wrote all that to say what? By your own acknowledgement blacks and whites didn't worship together. Blacks sang different songs, focused on different verses, and have a different style of worship.
And dumb minimization of what integration means didn't help your argument. Many of us have education, are working jobs, and have avoided trouble in a way that wouldn't have been possible for many prior to the Civil Rights Movement. But keep running with shitty misrepresentations. I'm sure they make sense to you.
