I have tried listening to Fox, and found i can't. Try it sometime. It's as much the method and tone as well as the blunt statements. Same topic presented by republicans or democrats sounds more gentle on pbs.
They do have a style that is grating on the nerves if you're not used to it. I'm trying to avoid being irrational politically by trying to find books by right wing authors as well as left wing. The problem in the US that makes this especially difficult right now is that the shrill voices are coming from the right and only those voices most of the time. I don't think it's sunk to that level in Canada though it may yet do so.
