> If the person is spewing anger, try to minimize the harm done by that anger by either asking them to stop or removing yourself and others from observing or participating in it.

No it's not. It's a tool. The problem here is that people are attaching emotions to tools and code, as though they were their spouse or children. Emotions are an irrational/illogical process, programming is rational/logical - don't mix the two.
