I'm going to disagree with this statement.
I don't believe the major media should be portrayed as anti-gun, since most, if not all, of them are well protected by hired gunmen and even with their own personal guns.
What they should be portrayed as is anti- second ammendment, anti rights.
They oppose the right of the common man to freely own guns as an unregulated right, not the ownership of guns by priveleged individuals or agencies. They do not want to remove guns from society, they want to restrict the ownership of guns to the elite and the various parties that the elite deem worthy of ownership.
While this may seem like word splitting, I think there is a discrimination between being anti-gun and anti-second ammendment. And it is this discrimination that could make the difference in swaying the public opinion on the matter. Most Americans resent being told that they are not the equal of others, that they are not good enough for the priveleges that those on top enjoy as a matter of right. This resentment must be played as a card in the game if we want to win.
