I know we seem authoritarian (we, who espouse rule of law) to them (they, who espouse rule of "feelings" -- theirs).
Yes, they are animated primarily by emotions not logic not rationality. Unfortunately the emotions that dictate their actions and underly their attitudes are hatred, prejudice, bigotry and fear. This is the source of the fanaticism we sense from them.
They are focused in a very primal sense on their hatred for fellow Americans who hold traditional patriotic and religious values. The combination of traditional religious values combined with traditional American pride are the witches brew that sends liberals into an uncontrollable frenzy of hatred and bigotry.
Admit to traditional religious and traditional American values and you are worse than Islamofascist murderers. Liberals would much rather exterminate YOU than they would Bin-Laden. To realize this is to begin to understand the bigoted, hateful, prejudicial nature of liberals.
Should they regain power be assured that they will target YOU and all you hold dear. Their focus and resources will be aimed at neutralizing and/or destroying your ability to exercise control. Any energy or resources remaining will be half-heartedly used to create the impression that they are confronting Islamic fanatics.
