---"He needs to be chastised for this nonsense."
Chastised?
It's his radio program and he can express his opinions on this issue any way he sees fit.---

He's free to give his opinions on political issues. That's what he gets paid to do. You can complain, but they will laugh at you. They aren't going to take your complaint seriously.
