How come liberals have led the charge to BAN rap music, use of the N word, baggy clothes & con radio?

They will do anything to win. Liberalism should not be thought of so much as an ideology as a state of desperation. After all, it is so much about change that it holds nothing sacred at all. Obama's chant, "change change change" pretty much sums up the entirety of their belief system. There is no such thing as a concept so absurd that a Liberal does not adhere to it, there is only an amount of time until it becomes mainstream liberal thought.
