I would compare ethics to swimming in a giant tub of ice cream (all the same flavor) with the rest of humanity. Everyone has a favorite flavor which their intuitions pick for them, but the world can’t fit everyone’s tastes. Some flavors are acceptable deviations, but others are painfully unbearable. It only makes sense to try and fill the tub with your personal preference.
