Maher is a voice outside of Christianity looking in, but that doesnt make his points less valid. It took me a while to break out of the war-like attitude I had and understand it wasn't biblical. Maher is right about torture as well. Why do Christians tolerate it?

He does go a long way with his points, using very broad strokes to talk about a lot of problems. Those broad strokes paint the picture of a lot of people who don't feel the same way. That's one of the reasons it's important for each Christian to make his or her voice heard. 

I'm anti-war, anti-torture and anti-big government. I don't want to see anyone harmed. I don't say that because I want anyone outside of Christianity to approve of me. I want to fall in line with what Christ taught. We are called to bring light and peace. 

Those who throw jabs have their own reasons, but it doesn't mean they don't see some morsel of truth. It can open dialogue to help us point the light not to how Christians are practicing Christianity, but to the Christ who came to save us.
