The man responded appropriately. He was constantly interrupted and showed that he had more self-respect than to subject himself to that kind of treatment. (Those idiots who support the idology of Fox will rationalize the demonstration of bullying by the Fox people as being on the right side--there is no way to get through to them and this man knew better than to try.) I am certainly he knew that he was going into a hostile environment but some people won't put up with that kind of hostility for long. I saw it as more of a statement of finality--as in, his final appearance on Fox.

Further, to follow the advice of Pakman--to interrupt the hostile one and then storm off in a huff--would make the idiots on Fox the sympathetic ones and paint the one who left as the bully, turning it into a "take my ball and go home" situation.

Some people like to be combative and some like to be conversational; this man seemed to be more of the latter and responded appropriately. Conversely, the Jeremy Glick piece linked by another poster, shows how allowing the true bully--whose name is on the show--one to drone on and on while sitting and tacitly showing apparent deferrence and respect will always backfire as they will edit and outright disregard the actual discussion and use it to assassinate the character of whomever they wish.
