Anyone who has been on this subreddit for long enough knows that most people would not understand the reason why the MRM exists, and believe it is unnecessary. So I've come up with an "elevator pitch" for the movement that concisely explains the rationale and goals of the movement:

We, as a society, have been aware of the discrimination against women for over a century. However, men are not immune from cultural biases and imposed social norms that affect their quality of life and opportunities. Gender norms go both ways: while women are valued for being beautiful and demure, men are expected to be tough and aggressive, even when not needed. We want men to be free to express themselves and live their authentic lives without the shackles of rigid gender norms, just as feminism fights for in women. It is important that we recognize that sexism is wrong no matter the target, and only when all sexism is addressed, can both men and women be free from it, and embrace their individuality.

Advice is appreciated. (I'm certainly not a professional writer)
