Atheists and Anger

Greta Christina’s posted a long, passionate piece entitled Atheists and Anger. I’ve been thinking about writing something like this for a couple of months, but now I can just endorse her magnum opus.
The bottom line:

I’ll acknowledge that anger is a difficult tool in a social movement. A dangerous one even. It can make people act rashly; it can make it harder to think clearly; it can make people treat potential allies as enemies. In the worst-case scenario, it can even lead to violence. Anger is valid, it’s valuable, it’s necessary… but it can also misfire, and badly.
But unless we’re actually endangering or harming somebody, it is not up to believers to tell atheists when we should and should not use this tool. It is not up to believers to tell atheists that we’re going too far with the anger and need to calm down. Any more than it’s up to white people to say it to black people, or men to say it to women, or straights to say it to queers. When it comes from believers, it’s not helpful. It’s patronizing. It comes across as another attempt to defang us and shut us up. And it’s just going to make us angrier.
