If by "demonize" you mean "letting them talk on the air so they sound like the rabid Chuck Norris wannabes they are" then yes, they do that.
I would LOVE to see some video from CNN or ABC or whatever showing us how, say, they "demonize" people that own a licensed handgun in their own house. Find some or join the Chucktown Express to Nopointville.
Nice out! It's not the people that keep "hand"guns in their dwellings that the media demonizes. You'll never get video of that because people are not threatened by what they do not see. It's those of us that walk around with it tucked in our pants about town for our family's protection. Those of us that have the "black rifles" as they like to refer to them. And those of us that know the truth about the government and the United Nations ultimate goal of disarming all American citizens. You sir, can spew all the "the government is here to help us all" nonsense if you want. But I for one will never buy into that.
