Mark C. Rosenzweig - I know this guy. Bad news. Not nice. He is in the forefront of helping Castro's dictatorship repress and jail Cuba's anti communist independent library movement. For more info on his terror go to this great site:

You can't get lower than Rosenzweig - he sends the nastiest e-mails to attack anyone who challenges him.
Visit him here if you dare:
