As much as we can accuse ethicists of living in the Moon, if there's one thing worse than being an ethicist is not considering ethics at all. If you haven't put at least a basic effort into rationally justifying your ethics, you end up choosing right or wrong based on vibes, including but not limited to positions such as "well life begins at conception so abortion is murder and always wrong", "this moral flaw may have been minor but that person is CREEPY and that confirms my suspicion that they're a MONSTER" and "noooo you cannot have a gender identity/sexual orientation that I don't understand, you must be a deviant and a pervert"
