That's an interesting view. I don't see it that way, though. I see anger as a perfectly natural reaction to some situations. The same as people naturally feel love or empathy or sadness, we can feel anger. To me, that's fine. It's what we do with anger that can make it constructive or destructive.
thats true - but I find I only do sensible things with anger once the anger has subsided..
Not that it doesn't have its uses - sometimes you don't have time to think and you have to react with whatever you've got - but I never make the best decisions that way, just the survival ones.
