Yeah, "Separate but Equal" was an odious fallacy the Supreme Court indulged. It was never enforced, and was impossible to guarantee anyway.
I should clarify that it was the equal part that was never enforced. The separate part was enforced-savagely in many places. Every inequality on the basis of race was a violation of Plessy v. Ferguson. To my knowledge, there were no prosecutions for violating that part of the law.
But it was a fallacy anyway. That those with power would treat equally those without was a fantasy.
I do use a digital device in my photographic pursuits when necessary.
When someone rags on me for using film, I use a middle digit, upraised.
