Write to them and request that Fox news be blocked from your lineup. We're boycotting Fox. If they tell you they can't because they don't have a trap in place ask them to create it and provide this service to their customers. If you have satellite it's much easier to call and have the channel removed.
Here's my letter part of it I borrowed from another Du'er who did the same thing.
To Comcast,
Could you block the Fox News Channel (42) from our home lineup? If you don't have a trap currently in place to provide this service to your customers I implore you to create one.
I consider their slanted journalism and misinformation to be a danger to our democracy.
I urge you to read the recent Pew Research report which found Fox viewers to be the most misinformed news viewers in America and research by the Program on International Policy Attitudes, based at the University of Maryland in College Park, which found that "80 percent of those who said they relied on Fox News .... believed at least one of the three misperceptions .
Thank You,
