Against Brexit but I didn't vote because I'm not a British citizen let alone a Brit. And I don't narrate documentaries although it might be nice to one day.
Nihil obstat (Latin for "nothing hinders" or "nothing stands in the way") is a declaration of no objection to an initiative or an appointment. Apart from this general sense, the phrase is used more particularly to mean an "attestation by a church censor that a book contains nothing damaging to faith or morals".
