We are made in the image of God. Part of that is that we want righteousness, and we want the best for each other. Part of that is anger. Part of that is love: and the two at times are aligned. To not allow this — to call all anger violence, and all leadership abuse, is to make us less than human.
And, more importantly, less like God. As you say, love does not prohibit anger. Although God is love, he is very capable of anger.
I wonder if Muslims view God more from the anger perspective, rather than that of love. If so, perhaps that helps explain the growth of Islam.

I finally figured out where the photo was taken. I lived on the North Shore for 10 years and am used to seeing Rangitoto from that direction. I was thinking Devonport but I see it is Mission Bay.
