Indecent Exposure

Laws against nudity are expressly religious in nature, curtail liberty, and have no secular purpose. The purpose of the law is to protect the populus from violence and exploitation, and to provide basic services such as police, fire, health care, etc., not to protect the delicate sensibilities of the populus.

If there was a law against gay couples holding hands in public, or a law against purple socks, there wouldn't be such support for it.
