The odds that liberal thinking is going to look defensive is due to the strength of opposition from those being the critical reaction.
Liberal attitudes allow for living with problems by a style of appreciation that is denied by the critical attitudes of judgment.
Appreciation gives us the effort to think harder than a critical reflex.
The challenge to reduce choice to appreciation is the introduction of critical thought.
The story of The Garden of Eden implies mankind lives in bliss until the awareness of unknown desires come to fruit.
I believe The Creator would warn Adam and Eve of expanding knowledge.
They were told that changing attitude (by gaining knowledge) would blame others if they became critical.
I don't think they were denied knowledge but misused it.
How the Creator receives credit has a critical cost or charge.
The reflex to blame, shame and threaten is in the knowledge of good and evil. Evaluation helps us conceive all the elements of a situation before judgment reaches conclusions.
The best antidote is to consider the vow, "for better or for worse."
Liberals try to see spending as a better investment while the critics look for the worse expense.
The simple truth is in appreciation until a critical impulse complicates it.
The best contribution of conservatism is conservation but the discovery of liberty is a liberal awareness.
The point of the truth is in how close it is to a conclusion or a conception.
Behavior can either contribute or eliminate values between being assertive and defensive, I have witnessed conservative behavior reuse (eliminated) points in defense and think they were being assertive.
It is easier to remind someone (reflexively) than introduce a new (liberal) idea, this is the difficulty in dialog between being relative and responsible for a future variation.
