Doing something so juvenile as an adult is a key sign of a liberal democrat. They cannot control their impulses, thet are easily programmed by the condescending media types found at NPR & MSDNC, and they are basically sheep following their particular “common sense challenged” herd.
The philosophy of the far left does not allow for tolerance. If you are with them on every detail, you are alright. Differ with them on any significant issue, and you are not just wrong, you are evil.
Remember the slogan: Conservatives think Leftists are people with bad ideas. Leftist think Conservatives are bad people with ideas.
This is because leftist philosophy has no room for unintentional, random, or God directed events. To Leftists, every wrong is intentional. Therefore, any thing they disagree with, was done by an evil enemy.
It is a return to witch-doctor theology, where every evil is the result of an intentional act.
