This is one of those fundamental "my way is better than your way" versus "live and let live" kind of issues. We each, of course, can have our own perspectives on whether we, personally, would do this-or-that to ourselves, and whether we find this-or-that attractive to our own eyes or not, but it is incumbent on us, living in a society with other people, to recognized and acknowledge that the purview of our perspectives don't extend past our own personal space. As long as whatever that other person is doing is legal, and sanitary with regard to their service to us, and in keeping with their personal perspectives on right-and-wrong, then we are obligated to respect that decision as a reflection of the inherent right of respect due to everyone.
