I'd specify that the specific type of male rage which the article is talking about is a sign of weakness.
We all make mistakes. We all get angry. Sometimes we get angry at other people when they make mistakes. Sometimes we can carry that anger with us for a long time. I can understand all this. I’ve done all these things.
What I don’t understand is this brand of masculinity that insists on continued anger, and on asserting dominance and control in a way that ultimately draws attention to weakness and fragility. It’s like we’ve empowered a whole slew of men to embrace childish behaviour in the belief that it makes them seem powerful.
That's a very different thing than just general "rage". Sometimes rage is an appropriate reaction to a set of circumstances. Personally I don't think men have many things that are worthy of raging about compared to women, but that number is nonzero.
