Nobody is suggesting that humorous comments are an "attack". The point of the article was to differentiate between the joking comments made by men and the more benign comments made by women. Making light of someone's activity is still belittling, even if not a direct insult. Even if not said directly, the implication is "you're doing something I find funny."
> people go "huh that's weird I have to say something let's try gentle humor"
That seems to be the crux of the matter: people who a) believe they need to say something at all, b) decide that it must be something "funny", and then c) actually say it out loud. Have those people ever stopped to consider that their opinion isn't wanted?
