If by 'against' you mean they cover what is actually happening, um, the media is funny that way. They were against the Nazis, they were against the Soviet killers, the murders in the Balkans, they cover atrocities all over the world.
The Israelis are now murderers in Gaza. The media is 'against' that, meaning they are showing what the IDF is doing. And if that is 'liberal' how old are you?
