"MRA" means "men's rights activist."
An MRA is a white man who insists against all evidence and decency that white men are oppressed and than women and minorities are "revered and privileged."
An MRA would never support the rights of those men who truly are at a disadvantage in our society: homosexual and black men. Instead, he leaves campaigning for LGBT rights and minorities' rights to the "evil evil cunt bull dykes" aka feminists.
An MRA sits on a huge pile of white and male privilege and keeps whining that he is oppressed.
An MRA loves Pat Robertson and Bill O'Reilly, thinks that Fox news is the one and only reliable delivery mechanism for news, is a psychotic bible thumper who believes that women were made from "Adam's rib," wanks to Rush Limbaugh, supports the religious right, and has never finished high school.
