Problem With The "Left"

The "Left" seems to be primarily defined by the "Right".  

The Right says that Lefties are "communists", then go on to define communists as "godless", who want to take away your freedom, and who promote all kinds of other "evils".

The Left seem to do little to counter or dispute these descriptions, and in other than rather specific ways does little to say who they are or what they stand for.  The Right is all about "Values", while the Left seems to have none -- at least the Left does not say what they value.
