In his dissent in Plessy v. Ferguson, John Marshall Harlan cited one of his objections to Louisiana’s public transit segregation law as being that it effectively left the execution of policy to railroad porters. Homer Plessy was a light-skinned Creole man whose family was free before the Civil War. He would have enjoyed roughly equal rights to Whites up until the first generation of Jim Crow laws in the 1870s. Harlan pointed out that the criteria for “White” and “Black” for the purposes of segregation was not solid, just being whoever was in charge of the segregated facilities looking at them and determining what they are.
There is nothing new under the Sun.
I’d say it’s also a problem that the sort of people who use the Internet to find people to beat up are idiots, so even if they aren’t going out of their way to victimize minorities, odds are they’ll just beat up some random person.
