“Mind your own business” is a common English saying which asks for a respect of other people’s privacy. It can mean that a person should stop meddling in what does not concern that person, attend personal affairs instead of those of others, etc.
Clear enough?
Nope. It still smacks of libertine libertarian nonsense that says my immorality has no impact on you or others, a blatant falsehood. Plus the clear implication is to say to us social conservatives, “SHUT UP”. Sorry mate, not gonna happen.
