"War" is an overused rhetorical term all over Washington. It's very much true that many reporters don't consider themselves as "anti-Christian," let alone warring on Christians. But if we rely on their self-perceptions, they also don't see themselves or their friends as "liberal." They are, in many cases, eager to promote a more "inclusive" Christianity, a creed with room for gay bishops and even theologians and pop authors who deny the divinity and resurrection of Jesus.
We can agree that the media are nearly 100 percent liberal on the top social issues of the day, and that reporters are hostile to the political agenda (social conservatism) of Christian conservatives, and are generally over-eager to make them villains with sloppy assumptions that these "fundamentalists" are just like the Islamo-fascists we're fighting. It's also fair to push back at reporters who feel free to use sensationalistic terms in their own precincts. How many times have we heard versions of Republicans waging "war on the poor," or "war on women"?
I think this quote sums up the difference. Republicans are accusing of making war on the poor, when they just have a disagreement about how best to help them. Meanwhile, the media actively belittles Christians and promotes theories that shouldn't pass the laugh test that work to undermine Christianity. They may not believe they are at war with Christians, but it's certainly closer to war than GOP policies on the poor are.
Then again, they don't believe radical Islam is at war with the West, so maybe their dictionaries are wrong from the start.
