Why all this discussion of who watches what cable news programs? What does that have to do with anything? We're discussing whether or not O will appear and why he should or should not, and all I keep hearing is "Fox is the most watched..." Who cares?
Look, if there was a network called "Burning coal is destroying the earth" network, would any of you want to appear on it? Before you get all gung-ho and tell us how "Oh yeah I'd love to straighten them out!," remember that you'd be behind enemy lines, you'd be cut off constantly, everything you said would be taken out of context. FOR EXAMPLE, the mod might say "So you admit burning coal emits sulfur." (you'd look stupid to deny it, it's a well-known fact). You'd say "Yes, but..." and be cut off with "So even though YOU ADMIT that burning coal emits sulfur, you still burn it! You hate the earth!" So the audience watching who hated you to begin with can now run to all his other coal-hating friends and say "Oh yeah he admitted that coal emits sulfur, but he doesn't care, he burns it anyway."
This overly-simplistic exhaggeration shows EXACTLY what would happen to O if he appeared. Absolutely nothing he said could possibly be correct, and the audience who by in large hates the man to begin with (due to the faulty information they've been force-fed) would use all the skewed information to hate him even more. Much in the way this is squawked across every conservative outlet, that since O won't appear he must be afraid or have something to hide, and all the conservatives flock to the bird bath and drink the kool-aid. Sillyness.
