None of my friends or I watch tv, and it is safe to say we are all very liberal, but hardly "crunchy". I just don't enjoy tv, it's so predictable, the ads make me crazy, and I just feel like my time is spent better elsewhere. We are all highly creative and intelligent, and it would be a shame to turn all our excellent conversations and activities to talking about tv shows.
I did have one person ask me once, upon hearing that I don't watch tv, if I went to the movies every night. She was baffled that I didn't choose to spend my evenings watching some sort of moving picture.
