Check out this video of a debate between William Buckley and Noam Chomsky from 1969. Isn't this a far cry from what passes for debate on television today? Chomsky and Buckley are probably more ideologically different than any two individuals you might see "debating" an issue on tv today, yet they still manage to remain calm and courteous. Additionally, note the length. The debate is long enough so that one might actually see the arguments fleshed out enough to allow a person to form an opinion on the subject being debated.
