Cultures, those collections of traditions, beliefs, and folk lore, that seem to be inviolate and beyond criticism or ridicule (according to political correctness), are antithetical to egalitarianism and both human and animal liberation.
Cultures are bundles of bigotry, myth, superstition, xenophobia, chauvinism, dogma, animal cruelty, and misogyny.
They are barriers to all we value in a democratic society.
Some leftists are so intimidated by the possibility that they might offend some minority, and appear bigoted themselves, that they defend the most archaic, ridiculous customs, religions, traditions, and prejudices as “cultural diversity.”
Shorthand for any attacks on cultures is “racism.” Exposure of bizarre rituals and cruelty is “intolerance.” Many on the left are engaged in unjustified bigotry similar to what those on the right seek to do under the guise of religious freedom.
As leftists, we accept people for who they are, not what they are.
Race is the single most stupid gauge of judging people imaginable. No rational person can justify racism.
But is is fairly easy to counsel against the beliefs and practices of ancient cultures. They should be summarily rebuked where they conflict with the rights of women, gays, people of color, animals, or any other oppressed group.
Cultures should be consigned to the dustbin of history.
