As a matter of moral principle, I reject the idea that there is an obligation to conceal the sexual parts of the body. I put it on the same level as the idea that there is an obligation for women to conceal their faces and deny their humanity.

To me, the bikini and the Speedo are on the same level as the chador : you may choose to wear one, but you do not have the right to expect others to do so, or to be angry if they do not.
