Oh, I think there is a secular reason, it's called germs and herp viruses and sweat and all the other stuff that our clothes protect us from spreading around. You want to sit in a nice, moist restaurant booth after a bunch of naked people get up?
If you want to understand Leftism -- and everyone needs to because it has been the most dynamic religion of the last one hundred years -- one good place to start is with San Francisco.
Or perhaps more precisely -- with nudity.
And even more precisely -- with public nudity.
Last month, the San Francisco Board of Supervisors voted by the barest (pun not intended) margin -- 6 to 5 -- to ban public nudity. By public nudity, the law refers only to displaying one's genitals in public. San Francisco women are still free to walk around topless. But that is not unique...
Maybe restaurants can provide disposable hygienic seat covers like public restrooms.
BTW: There have been studies to find the most germ-laden places in restaurants. Surprisingly, one of the most germ-laden places in a restaurant is--the menus. That's because the menus are handled frequently by every patron and every waiter, and they're almost never cleaned.
Either way it will encourage me to eat more at home and pack a lunch at work.
