Let's Get Naked!

So, we have an art exhibit in France where you must strip down naked to enter, followed by a drink and chat. The aim of the macLYON exhibit is to challenge the notion from Rene Descartes that "I think, therefore I am," but instead we are above our bodies. Next, we have a German landlord who deigned to bathe in the nude in the public courtyard of his building. The Frankfurt residential building included an office floor. The company withheld rent when they objected to the naked sunbather. Why is there so much controversy over being...naked???!
