I've written before about anti-gay McCarthyism in Nigeria. A few years ago, the federal government wanted to ban all free speech that argued in favor of gays as human beings. Specifically, legislation would "punish individuals who witness, celebrate with or support couples involved in homosexual relationships" with a 5 year prison term.
And then I read something in Wikipedia that sounded nearly identical to what the Nigerian federal government proposed.
An entity enacted a law that stated:
"Any person...who shall be guilty of printing, publishing or circulating printed, typewritten or written matter urging or presenting for public acceptance or general information, arguments or suggestions in favor of social equality or of intermarriage between [two groups], shall be guilty of a misdemeanor and subject to fine not exceeding five hundred (500.00) dollars or imprisonment not exceeding six (6) months or both."
The entity was the US state of Mississippi.
The two groups in question about which it was illegal to ARGUE that there should be any equality between them were blacks and whites.
