They can't do you any harm. If we accept the view that government is the Great Protector, then it logically follows that whatever the government does not prohibit is okay. As we all know, this is not the case. Each of us is unique. We have our own set of needs, wants, tolerances, reactions, strengths, weaknesses, and abilities.
Some people are deathly allergic to wheat, while others can chew double-edged razor blades.
To be perfectly normal is abnormal. Government-set standards for personal behavior are based on the average. By making the norm the law, the government encourages us not to explore our own strengths and limitations, but to adapt and fit in as best we can to the norm. The strength and power of the diversity within us are never fully explored. Our depths are never plumbed and our heights are never scaled.
