> America’s is segregated by race.

That was not true in any of the prisons I was in in Texas. There were four that I lived in over ten years and several others that I traveled through. I've heard about it being the case in some prisons, but to present it as a universal truth is wrong. The most strictly segregated prison system I've heard of is California's, but it's based on alliance rather than race alone. The AB-aligned whites are allied with Sureños (a Hispanic group) while blacks are allied with Norteños, and fraternization is fine within the alliance but not outside of it.
