Hillary Clinton said she found her voice, but that is not what really happened. What happened in reality is that she dropped the disguise.
Pundits everywhere translated her emotional moment as weakness, that she broke down under the pressure and surely would not be able to continue. But note, she did not cry as some claim.
The emotion that she showed is something possessed by all humans, but if a man exposes his feelings, he would be perceived as weak and not manly. You have to be macho, you can't cry, but if men did, and some do in private, they would be psychologically stronger. This can be seen among men, mostly by how they live their life. There are those who do the physically tough jobs and play the physically demanding sports, and at the other end are those in the more sensitive jobs who do not feel that they must portray themselves as macho. These may include those who work in health care, human and animal. These are also the homophobes and the gays on one end and the other.
Hillary for the first part thought she had to play that game. This could be observed by her speech, the shouting, also the forced laugh, best described as a cackle, when she thought she had to mask her femininity in order to appear tough.
Emotion is not a weakness, it is a strength, as women are also stronger than men in several respects. While men are more likely than women to run from the sight of their own blood, women are also better in enduring pain. If men bore children, our birthrate would not be as high as it is today
