It's amusing, to me, that some folks are so willing to take advantage of "free" offerings, often with gluttonous zeal, yet, then get so bent out of shape when asked to make a contribution. Public television, public radio, and websites, such as the FDP and this one, aren't free for everyone. Someone has to pay the bills.
The idea that they're just out there, free of charge; to claim some entitlement to use them, without support, is a pretty curious attitude. Kinda like the music downloading argument - "Why should I have to pay, when it's available for free?".
