"as long as nobody knows, it's in private, and I'm not affecting anyone else, it doesn't matter" actually false.
the way you choose to conduct yourself in private shapes your habits and therefore the formation of your personhood, and thereby ripples outwards to affect your connections with others--not just in their opinion of you, but possibly in their own actions as well.
you are not an island in this world, and the things you do will be refracted back at you, even if you never speak a word of them. how you choose to grow yourself as a person is important because you are one alongside many. large changes (and their consequences), whether they occur in family, smaller friend circles, or on a society-wide basis, are never enacted from nothing.
your personal actions do in fact have wide-spreading consequences among your smaller circle and ultimately your community.
