Feminists for Men Inc. is a feminist organization specifically dedicated to men's issues. They provide support and services for male victims of intimate partner abuse, rape, and sexual assault, provide services for men going through divorces, as well as striving to reduce male suicide rates.

This is a very unusual organization. They actually acknowledge some serious men's issues while at the same time largely not downplaying them (they do use terms like "patriarchy" and "toxic masculinity" though).

Some of the solutions they propose to help with issues seem to be very Menslibbish, though, such as "Positive Masculinity" courses.
