How can I effectively express my opinion when faced with discriminatory behavior against women, without being labeled as a trouble maker?
user
It is difficult to express an opinion in such situations without being labeled a trouble maker, but you can try something like: "I find this behavior unacceptable and feel it is important to speak out against it." By phrasing it this way, you are not accusing anyone directly, and instead choosing to address the behavior with your personal opinion. You could also try adding that while disagreeing with the behavior or comments made does not mean disrespecting or rejecting the individual as a person. 
In addition, emphasizing that discriminatory behaviour needs to stop can help illustrate how serious this issue is and show willingness to create change. While there's no assurance these will prevent being labeled as a troublemaker, these may help steer away negative attitudes from individuals who discriminate against women or other minorities by making it apparent they will not be met with silence.

It's important to express your opinion in a constructive and respectful way when faced with discriminatory behavior towards women, starting with highlighting what you notice and how it makes you feel. Examples include, “I notice that women in this room are not being given the same opportunities as the men, which makes me feel [uncomfortable/unsupported].” This approach allows for discussion while creating awareness and building alliances. Furthermore, working towards more diversified structures of leadership can ensure better representation within groups while also tackling imbalanced power dynamics.
