Daman. PBS and NPR have proven to provide more accurate news than any of the outlets. I have posted research on this before. PBS/NPR viewers knew the facts more than CNN/FOX/CBS/ABC viewers, who got 1/3 facts wrong consistently over a very large sample size.
PBS may have a liberal programming and commentators, but their news is accurate. Stations like CNN and FOX let people fill in the blanks themselves whichc often lead them to false conclusions. Look at the amount of people who though Saddam was behind 9/11, that didn't come from PBS and NPR

Tax dollars are also funding pentagon TV
Well . . . OK
but that really is not my major issue PBS or NPR.
Im also aware the PBS veries from state to state.
How would you guys on the left feel if PBS employed Rush limbaugh, Oreilly, Glenn Beck, and other charismatic figures from the right - played tons of NRA, Pro-life videos, etc that cost 100,000's of dollars to produce - and then had one or two 30 min. slots a day of stoned hippies that cant articulate a single thought to come on and offer rebuttels? And then on top of it, asked you to shell out money to fund it?
Thats an equivalent to what is happening with PBS in my state/city right now. Its just not right. (Unlike the left who want to censor FOX) I would have no problem with it at all if it were privately funded. But its not. And the couple hours they spend broadcasting their less biased news, is not worth the amount I give them in tax dollars to spread their leftist message.
