...and in classic equivocation, when you ask many negative people if they are FOR anything, rather than just AGAINST stuff, they will answer.. "Sure, I am for lots of things!" ...and then give you a list of things which, when analyzed, involve denying various rights & freedom to others.

"I am 'for' acknowleging the Christian God, and 'for' the Right to Life, and 'for' the rights of a businessman to choose who he must serve, and 'for' the rights of a business to regulate itself, and 'for' parents right to discipline their own children...." etc.

I'm sure everyone could add many more examples of superficial descriptions of 'positive' attitudes which are barely disguised restrictions and indicate a basic negativity and desire to reject ideas & rights which they deem unacceptable.
   In some cases, it takes some careful sorting and extraction to see what is really being said.
   All that is yet to be worked out is how much of this attitude is, as Jack suggests, 'predisposed', and how much is culturally inculcated by family, school, church...etc.
