The Men's Rights Movement (MRM) is a misogynistic movement that advocates violence against women and girls.
Multiple members of the MRM--self identified Men's Rights Activists (MRAs)--have committed atrocities and mass murders. Marc Lepine killed 17 women on a university campus in the "Montreal Massacre". Tom Ball firebombed a courthouse and wrote a manifesto encouraging others to bomb government buildings that is posted on major MRM websites like avoiceformen.com. Elliot Rodger, an active MRA, shot and killed at least 7 young women and injured many other people at random. Rodger is being celebrated as a martyr and hero by the movement, which will likely cause other MRAs to emulate his crimes.
This is what the MRM does and action must be taken against them to protect women and girls.
