Religious people do not have much faith in God do they?

See the premise of the Christian faith is that God is all powerful, all seeing, all knowing, knows when you're sleeping knows when you're awake. So why do Christians feel the need to protest and create so much noise about certain things when an all powerful, all knowing, all seeing God would already be dealing with it in rather mysterious ways I might add.
There are some things that seem a bit "off" to me though. Let's take pro-life Christians bombing abortion clinics and killing people. Now I'm not going into how ironic a pro-lifer killing people is, but just thinking about this;

I am not a religious person, I don't subscribe to any specific faith, I simply state that I do not know, yet I would never dream of killing someone for simply having a different point of view than me. So a person subscribing to the 10 commandments definitely should not kill someone, unless they want to end up in Hell that is. Not that I believe in hell just making a point.

A Norwegian Islamic fundamentalist said "I put my faith in Allah, he will take care of me and he is the best planner that exists" as much as I hate religious fundamentalism I respect where he's coming from. He has faith in his God to take care of him, and not only him but the world.

If I was a religious person, I might disagree with stem-cell research, abortion, drug use, promiscuity, pornography, prostitution, or as I call it "Tuesday" but I would trust in God to deal with it, and judge everyone at the time of the apocalypse. Doesn't God say in his word "The Bible" that he is the one to judge, not anyone else? In that case how can any Christian defend being judgmental of others? According to the son of God, Jesus,  one should be tolerant of sinners, somehow the behavior of most of Christian interaction I see is far from tolerant.
