Do Conservatives think just because they have been told a source is bad it means the source's claims are false?

No, it means one should search for other supporting evidence, and make an informed decision.

No source is 100% accurate, because human beings are not perfect.

Most media matters claims are false though. We could waste our time debating each claim they make, but the end result is always the same. It's the Chicken Little effect, media matters keeps crying that the sky is falling so we don't take them seriously. Maybe, once in every 100,000 claims they make one winds up being entirely factual, but due to past experiences we don't waste our time with them, and neither should you.

There are good reliable sources and unreliable sources. Even a blind squirrel finds an acorn once in awhile. If the story is true and based on facts then you can not kill the messenger for telling it no matter who it is. But when the messenger is biased, nonfactual, and many times wrong, then they lose their credibility.

Not necessarily

The claims need to be verified

Even the New York Times have been found to falsify stories, and their stories certainly need to be verified.

Some organizations just get a reputation of falsifying things, twisting information and suppressing news stories.

They just need to be verified and scrutinized more than other sources, that's all

Unfortunately for Obama, no, conservatives do not buy such BS.

Obama always tries to dismiss bad new by attacking the source, but conservatives know better.

I will generally look at the source skeptically and investigate their claims. But I pretty much do that with all sources anyhow.

Not necessarily. But, one cannot avoid remembering past biased claims from the same "source".

No that would be libs ranting about Fox News. I have watched it now for several months along with Headline News and CNN plus my local channels. I have yet to see them do more than report stories like anyone else. Am I missing something or are liberals having drug induced fantasy.

So if I use Rush Limbaugh's site as a source, you won't question it?

What's the claim?
