I'm a "card carrying" member of the ACLU -(which plenty of people of Fox's ilk think is a terrorist organization)- and we've defended far worse than Fox.   We've defended NAZI's and KKK'ers, among others, because freedom of speech is a core requirement of a free society.

The First Amendment is under threat all over the US because people don't "get" it, or even know what it is!   A few years ago a museum in Chicago (the McCormick Tribune Freedom Museum) decided to celebrate their opening by commissioning a serious poll of 1000 Americans, asking them if they could name the 5 freedoms protected by the First Amendment, and the 5 main Simpson's characters. About 1/4 of respondents could name the Simpson's characters.

Exactly ONE person (out of the 1000) could name the 5 freedoms in the First Amendment!!!!    So Fox should be the LEAST of our worries!
