Among their many odious planned cuts, the Republican-led House has suggested cutting all funding to PBS. This is a pet peeve of theirs and has been for going on fifty years. (There's a video out there of Mr. Rogers testifying to Congress on the importance of PBS, and if that doesn't convince you, you are dead to me.)
Practically speaking, I'm more outraged at the gall and heartlessness of some of these cuts rather than fearing their passage, as the Senate and President Obama have no reason to accept this nonsense.
But here's another good example of why PBS matters. If it's too small below, either click the image to enlarge or follow the link in the prior sentence.
