Talk radio has a propaganda aspect influencing masses, that I am not fond of, and an educational aspect that is good. You hear not just pronouncements, but arguments and discussions.
I listen more to NPR than to AM radio to get familiar with their reasoning. Does not mean that I agree with them, but I am sure that when I take a position I know what the counter-arguments are. Some here have a curious view that they refuse to listen to the other side – and then pronounce their judgment based on quotes they picked up somewhere. You can not be sure that you are not being biased. You see that a number of reasonable people found something in Talk Radio, so you should investigate and make a reasonable judgment.
PS It appears some liberal-minded Israelis have more integrity than Americans. A story that one Israeli academic told me: “I chose” not to be observant … Then, my older son, growing up, started mocking Datiim. I told him – if you want to talk like that, you need to at least know what you are talking about. So, he went a took a class. Became shomer Shabbat. Does not eat in my house anymore. Then, my 2nd son – same story repeated… (One of them is involved in right-wing Israeli politics). <end of story>. I give this guy a lot of credit – especially that he said the same thing to the 2nd son after what happened with the first.
