How about sweeping TV out of your life for 30 days?
During last year's US presidential election, I sat with my wife and her parents to catch what were supposed to be a few entertaining minutes of the best parodies of American politicians. Two things struck me: the parodies weren't funny; and the language was lewd and vulgar in a manner that would never have characterised conversation in our household.
We shut the TV off in mid-programme. But the thought crossed my mind: just how bad would TV have to get for Christians by the thousands to turn it off - maybe for good?
