Yes, that's precisely what it is. Moral judgements based on outdated ("conservative", especially clerical) understandings of the world, wrapped in some delusional sense of "objectivity". Only the scientifically and philosophically illiterate fall for it. In German, we call it Bauernfängerei (swizzling, duping; lit. "pawn catching").
