I don’t understand what this has to do with masculinity. These people recognized the danger and behaved heroically to try to protect people and help them escape. I give them my respect. But if it had been a woman who threw the chair through a window and helped people escape I would still call her a hero, not masculine. Think of female members of the military, athletes, EMTs, etc. who could have done the same had they been in that position. Acting heroically is not limited to one sex.
I completely agree.
