La Volpe
Sage
Men showing vulnerability is a strength.
This might be true in some cases, but remember that (especially) men tend to form hierarchies, and showing vulnerability makes you, well, vulnerable.
In something like war, if a soldier sees his general crying over a wound (no matter how grievous), he's not going to think that his general is strong. He's going to think that he can't count on his general anymore. And that maybe someone else should be taking over, since the general can't hold it together.
I.e. Showing vulnerability in dangerous situations is most definitely not a strength. At least, not from another man's perspective, I don't think.
