As a rabbi, I am enraged not at guns but at the casual violence afflicting our country, and the way we have grown immune to it. I do not accept the NRA's claim that "guns are not the problem," but I do agree that guns are not the main problem. This is a moral crisis, and it requires a moral response.
Climate change is one of the greatest moral disasters of human history, because the people who will suffer the most have been the least responsible for its cause. Those of us in the developed countries somehow think that we will escape its results, turning away from the hundreds of millions who will be caught in the whirlwind of misery that is coming.
