I think by calling these people 'liberal' we are making a big mistake. They are not liberals. They are radical leftists. They have no resemblance to liberals of the past.
Remember, these are the very same people who were willing to burn Chicago to the ground in 1968 because the greatest liberal of his generation, Hubert Humphry, won the Democrat presidential nomination. Since then, they have purged the Democrat party of liberals. It is now the party of hard, radical leftists.
Lets start calling them what they are -- Radical Leftists!
