Its frankly a garbage definition. Women are dismissed for displaying any emotion or for even
potentially showing emotion. It's used to dismiss them as irrational, unprofessional, fragile, out of control or compromised.
In a
landmark 2001 report on sexism in the courtroom, Deborah Rhode, a Stanford Law professor, wrote that women in the courtroom face what she described as a "double standard and a double bind." Women, she wrote, must avoid being seen as "too 'soft' or too 'strident,' too 'aggressive' or 'not aggressive enough.' "
There's a great story in there about how a female lawyer had a motion filed against her before a trial, asking her not to cry but couldn't get angry about it because that would "prove" shes too emotional. This is just from one field but its fucking everywhere. Women are too emotional to be in the military, police, business, etc.
The movie isn't subtle about it.
Potential theory.
