> Using that definition, censoring all publications of a given group (say, black people) would not be censorship
It's not censorship, it's discrimination. Bad thing, but different. If it was censored because these people write about specific racial issues, it'd be censorship. If it's blanket denial regardless of the content, it's racial discrimination, not censorship. It doesn't mean it's not bad - one could argue it's even worse since it doesn't leave you any chance - you could probably talk in another way to route around censorship but you can't stop being black - but it's not that issue, it's a different one.
Imagine now that you ban all writings from communists, including their love stories. It is not racist, and according to the definition it is not censorship. This form of behaviour was used a lot in ancient regimes, and known as censorship.
The definition you use seems to be a legal one rather than the usual one.
