"I’m not going to suggest a solution to the problem of men clamming up." If not, then perhaps that's the wrong problem statement, and solutions will become more readily obvious and suggestible when not coached as the problem of men.
That's as candid as I can make it, and I feel that I have to use a throwaway account to do so.
Even when phrased that way, I don't perceive that the author is _blaming_ men. The author is critical of the mob, and the dangers of being incorrectly perceived as sexist and ruining one's reputation. You may insist on your interpretation, and fixate your attention on a couple of sentences that ring the wrong way to you, but I think you are missing out on the nuance.
