Here's an excerpt from one of the Amazon reviews:
If intolerance of individual opinion is one of Maher's targets, another is stupidity. He is brilliant at identifying nonsense and characterizing it as such. He is also unswerving in calling a dime a dime. For instance, he points out the cowardly lack of courage shown by the media for referring to Strom Thurmond's fathering a child by a black servant in the 1925 Jim Crow South Carolina as "having an affair," as if an 18-year-old black servant had any choice in the matter. Maher calls it what it almost certainly was: rape.
But as he calls our attention to one political issue after another, Maher laces it with humor. So, in the end there are two very good reasons to see this, first to be entertained, and second to be informed. Either reason would be sufficient on its own, but together they make this a must-see.
I agree. Find a way to see this DVD. You'll be glad you did.
