You bring up good points but there still is a need. There are plenty of people who wont even consider news that isn't on TV. Having a mainstream channel that disagrees with Fox and CNN would be a great thing IMO.
I'm not so sure. Of course some people are completely closed minded, but I think there is still a lot of ignorance out there that can be cured. You wouldn't know it staying on sites like this one but there are a lot of people who's primary source of information is the TV and they'll probably give most things they see on there a chance.
Give it time. I'd love to know how many racists reconsidered their world beliefs as a result of their children dating someone outside their race - simply having to deal with something on a regular basis can acclimate you to it and make you think a little more critically about it.
I am not a fan of Fox but I understand what you are saying. It would be nice to have a fresh way of checking the news or view it from different perspective. Current way of presenting from any news organization is awkward. Politicians are polarizing the nation and news organizations are feed to the fire. That's why I stopped watching the news channels. I find this peaceful and healthy. Sometimes I think we are going freakN backward as a country. It's an insult to our founding fathers and the American way.
I can't think of one instance when an argument that starts with, "There are plenty of people who..." should be convincing. Here in NC, when the governor and legislature made their final push for a lottery, the governor said, "We're at a competitive disadvantage with surrounding states who do have a lottery." Which is a fancy way of saying, Everybody's doing it. We need to start a huge advertising campaign to entice our poorest and most ignorant people to gamble.
