It depends on how you look at it, the best radio hosts (Old Stern, Bob Grant, Limbaugh, etc....) know fighting with liberals (and vice-versa) makes the best radio, etc.... Alas everyone is so scared of losing advertisers, and a few days of social media upheaval, that you never get real discourse anymore. And then with each successive hiring and firing cycle it moves more left or right, but always more milquetoast.
It's been going on in big media for about 30 years now.
Thank God for podcasting.
