I've long held that 'Liberal' thinking (the extreme kind) is a form of Mental Illness.The liberal mindset is a very illogical and scary thing.
Liberals tend to be moved to 'emotion' easily and will act upon that alone. Any attempt to bring facts or logic into the mix...is viewed as an affront to their sensibilities.
I also question their principles and moral plane. Many are more than willing to do or say things (not generally considered acceptable) in order to achieve their goal. The mindset seems to be: ' The End justifies the The Means'.
There is clearly a cultural war at play in our society.
