Or rather, it means that it's not necessary for every man to pipe up every time to assert their niceness and lack of entitlement attitudes. A fact that all reasonably intelligent, rational entities involved in this discourse understand. If you're not the one being targeted by the claim, then it's not necessary to defend against it. And if the claim is explicitly "all men", then the claimant is clearly irrational enough that defending against it won't do any good anyway. Getting stridently defensive does not speak well to one's assertion that one is not part of the problem.
Perhaps you shouldn't expect people who aren't in your particular clique to implicitly understand that when you use the general word 'men', you really mean 'some men'.
Adding the word 'some' before the word 'men' isn't so difficult or time consuming. But I suppose it takes away from that self-righteous feeling you get when you say it, as well as afterwards when you get to arrogantly assert that you must be more rational or intellignent than people who don't accept your particular phrasing.
Personally, I tend to go with more precise wording so that there can be no misunderstanding.
