A north carolina segregationist who graduated college in say 1940 saw their political stance go from moderate & mainstream to fringe in their own lifetime. The fact that social-political culture norms shift isn't a very interesting or useful statement about the people it shifts around.
Maybe not when it shifts in a lifetime, but I beg to differ when it shifts in less than 10 years. It was also not meant to be an interesting statement about the person, rather the shift itself.
The rest of that sentence is important don't cut it out! It's not an interesting observation about the individuals; it certainly is about the cultures though.
Sociologists and historians both spend tremendous amounts of time on this, some devote their enter careers to small facets of this single dynamic.
