25% Are "normal". They go to work, school and/or church. They try to live life and stay out of everyone else's way.
25% Are not so "normal". They can function in society, but you don't like them. They don't even like each other.
25% Are less than not so "normal". They are non-productive members of society. The top two tiers are paying for their existence.
25% Are bat-shit insane. Murders, Rapists, Truthers.... All needing to be locked up and the key thrown away.
