Perhaps this is, indeed, conclusive proof that men aren't very good at expressing their feelings; but I take it more as evidence that men don’t think of themselves as members of a social collectivity called "men" in which they share mutual interests. Women have been parading a sororal solidarity with all women for the last 50 years which now seems to entitle all women to speak on behalf of all women at any moment because they all, supposedly, share the same interests and outlook. Most men don't begin to see other men in that light at all.
