A law implicated by liberal ideals isn't implicit of its relatives being liberal. It's a two way street, aswell -- it's a protected freedom. It's a freedom (conservative) protected (liberal). News stations are NOT inherently liberal and do NOT all support liberal ideals. Using this sort of information to try and state that Fox may be credible is absolutely atrocious. Again, see that nonbiased study showing how illiterate Fox News viewers are in comparison to others.
Protecting a freedom may be liberal, but to state that the people who promote these freedoms ARE liberal is hilarious.
You don't seem to understand. The press don't just promote these freedoms, they only exist because of these freedoms. Whether they are intentional or not about it, what they say is usually liberal leaning. The exception is when they are intentionally right (Fox News)
In order to get any split issue information evenly, you need to take from a variety sources. Which means that someone who looks at Fox News as well as other sources probably gets more information than you do.
As for your survey. It is essentially: "People who look at only conservative sources are more likely to believe stupid things conservatives say." I can guarantee you that people who look at only liberal sources are more likely to believe stupid things liberals say.
