But if you're the kind of person that thinks alien abductions are real, climate change is not, evolutionary theory is a fraud, government should stay out of our lives except for abortion, and so on then you will probably think NPR is a biased hedonistic den of sin.

NPR is far from unbiased.

Here's a serious and legitimate challenge, find me a concrete example of bias in any of NPRs news programs. (Morning Edition, All Things Considered, Top of the hour news updates).

The more editorial programs on public radio (This American Life, On The Media) are more opinionated, and the quality of local news is only as good as your public radio station, but NPR News is as clean as an organization as there has ever been.

NPR is roughly middle of the pack for the left-leaning organizations.

Here is a well done statistical study on the subject (jump to the end for nifty charts):

That's a fundamentally biased study that put Fox News in the top 5 least biased news sources.

Unbiased media doesn't exist anymore (if it ever did).

It never did

Sure, but what in your option is a less biased TV or Radio news source?

There aren't any. People use the words "biased" and "unbiased" mainly to express degrees of agreement.

Everyone's view is fair and balanced in their own eyes.

The biggest source of bias for PBS Newshour and NPR is the ITV reporting pieces that they occasionally use.

It's so obviously biased and emotionally charged. Makes me cringe. But it's pretty detectable bias so it's easy to disregard.
