Seeing as they still count for course credit, I don't think Harvard considers them to be jokes. I will take the highly paid accreditors at Harvard's opinion over yours, sorry mate.
I've taken classes at community colleges and I have a degree from an Ivy League school. There was absolutely nothing wrong with the community college classes, and I learned a great deal from them. I don't know where you got the chip on your shoulder, but I hope no one reads your words and gets the mistaken impression that community college is somehow lesser.
