My experience with liberal talk is they simply repeat the top-of-the-hour news; to wit, they simply echo the MSM employees' feelings. The only challenge was what names to call conservatives.
Conservatives speak for those of us who challenge the MSM employees' views.
I recall the early days of modern talk radio -- late '80s and early '90s -- the most oft-heard caller comment was "I didn't know others believed as I do!"
I recall decades of electronic medium when one hour a week of Buckley's Firing Line was "all the fairness conservatives needed."
Liberals have no intellectual, scientific or open mindedness honor. They always come from a hidden agenda (shuting people up and reducing vocabulary to their level), while they will accuse others of the same intention and of doing politics.
Just like the pedophiles of Soddom accused Lot, they think Jesus is a homoerotic thing for christians. They are completely blinded by attrotious lusts and satanic tyrannies. They are dangerous backstabbers. Psychologists are doing a bad job of warning us.
