I'll respectfully disagree with this premise. I believe that society has changed enough where men are more and more frequently comfortable enough to show emotion in public.
I don't think there is any lack of public emotional displays from men in contemporary society. It really depends on the type of emotion we're discussing. I tend to agree with TB that men are on balance much less likely to display the sorts of emotion I think
he means.
For instance; I don't recall ever seeing a man cry at his desk because someone upset him or was passed over etc, I've seen women do so
many times. I don't recall ever seeing a man cry because his girlfriend said something insensitive, whereas I
have seen many girls in tears because of some offhand comment. I don't doubt that in these instances they may have
wanted to, but felt they couldn't, or shouldn't. Isn't that what TB is getting at?
I'm not suggesting that suppression of (public) emotion by men (or women) is a good thing, that it's right or wrong or that it's absolute, merely that, in my experience it's just a common characterisic of
men to 'hold back the tears'.
I agree that it's changing and become more acceptable, or rather less 'unacceptable' for men to show such emotions; but I also think (at least on some levels) that men and women have
fundamentally different ways of handling stressfull situations. For the most part, I also think that men are less proficient at dealing with emotional stress. There are doubtless a wide and debatable range of reasons for this, some societal, some probably evolutionary, some merely unfathomable.
