Colbert Report: Funny or offensive?

For years, the Colbert Report on Comedy Central has been highly praised for it's fairly hilarious portrayal of Stephen Colbert as a right wing news reporter. He satirizes a right wing commentator that you might find newscasting on Fox. He makes fun of Republicans while he is actually a Democrat. He clearly is over-exaggerating how Republicans act, implying that they are intolerant and stubborn. Though he is really only teasing, many people take offense to his jokes.
