Do you think liberals and center-left people should condemn actions against Glenn Beck and his family?

I don't agree with Beck on really anything. I'm a center-left person and I believe people in our cause should condemn those who were harassing him, his wife and their daughter in New York. I find such behavior to be childish and some of the words used were uncalled for and disrespectful. We can get our message out and be respectful. What do you think?
