In the legal sense I meant (it is not allowed). And very few people are intentionally of consciously discriminating. I wanted to contrast that to practice: human features that gatekeep people of color and so on. Hope its clear now.
Today's twitter row is the "cancellation" of a history broadcaster for using the phrase "so many damn blacks" in a video, which is probably not a criminal offence Mark Meechan notwithstanding, but is definitely unambiguously racism.
Employment discrimination and the set of things covered by equalities law is the _beginning_ of tackling racism, not the end.
I boggle at what description of "in theory" this could conform to, other than simply defining it out of existence.
