I understand "private" stuff -- i'm not for it myself; what about a "public" morality? But, why doesn't making laws about a "red light disctrict" not fit into "protecting the rights of others"? Why shouldn't laws regarding "red light" districts be made? What's bad about them? And, does keeping order have only to do with "protecting the rights of others"? I would think that by "protecting the rights of others" you'd end up placing some on the margin of society...
