A movement to promotes the rights of men.
It fights for the political and legal rights of men etc.
But it also fights for the emotional rights of men. Many women have a practice of tantalizing men with sex. It has been likened to holding a plate of food in front of a starving person and they telling them they can't have any. Which most Masculinist consider to be emotional cruelty.
They are committed to fighting all the tiny pussy brained feminist of the world.
Today men are considered to be stupid and immoral etc by feminist and there crones and it is high time to put a stop to it.
