In contrast, most radio talk show allow for listener calls. Radio commentators have to defend their opinions on the fly. They hear objections they have never contemplated and they are scolded by experts they never contacted. Liberals do poorly in verbal defense as their opinions are fluffy feelings - - facts are hard to fudge.
Isn't the logic here
the more likely someone is to disagre with liberals the more "extremest" they are.
By this logic if 99% of the public were liberal hating dedicated conservatives then they would be extremists and the 1% would be considered mainstream.
The correct analysis is that the more someone listens to talk radio the more informed they are, the less likely you are to agree with liberals.
