Anger can come from betrayal. The very specific God as described in the Christian bible would carry little weight as an idea, were it not for growing up around only believers. Christian authority figures such as parents, pastors and teachers are betraying the trust placed in them. Imagine finding out as a teen that your entire social support structure-- teachers, pastors, even your own parents-- have been cogs in a giant lie-manufacturing machine. When I was growing up, I heard them spend hours every week begging and cajoling me to believe what they were saying. I think that request obligates them to excercise the tiniest bit of responsibility to be right about it. By faith, they don't. Young people need better guidance than that. It's a betrayal worthy of inducing anger.
