They mention the rightist argument and the centrist one, and not the leftist one, so it's biased towards the right.
They present the leftist view but not the extreme leftist view of total pacifism. Just like they don't present, say, an extreme right nazi view of nuke all the untermenschen.
The mainstream media focuses on the center, or the center-right, or the center-left, as that is where the majority of their viewers lie. They do not focus on non-mainstream views, excepting as special interest stories or maybe an occasional here's an alternative view or an interview with an interesting person.
Those are about protests of anti-wars, not the media itself questioning the legitimacy of the war. The media never say: Now we have "blah blah" talking to us about why the US has no right to be in Iraq.
Sure it does, I've seen it a number of times. But have you ever tried searchin CNN, it's a pain the neck. There's way too many stories.
It's not just extreme left. People like social democrats believe that the US has no right to be in Iraq.
But not from a pacifist position.
The social democrats are against the war for pragmatic reasons or because it's the wrong war or they don't agree with this particular war.
Your pacifist position is the extreme left.
So only people who qualify are given a real voice?
Only those who enough people are going to take seriously are given a "real" voice. But nothing is stopping extremists from making their own media.
I want media that mentions my views.
It mentions them, but only in relation to what the viewers will care about them.
