Well, a 'Men's Rights' movement/organization isn't allowed to use the distortion, propaganda, and generally foul tactics used by the feminist movement.
But, as Bill Pyne used to say,"There's great fellowship in a good cause." That would seem to include such groups as mensrightsnews.org, the American Coalition of Fathers and Children (acfc.org) and others. There are whole sectors of the economy to be 'masculinized', i.e. their opportunities made more available to men. And much law to be reformed and made fair to men.
And by the way, how's the Men'sRights Ping List going here at FR? Is there one?
I don't know, but those other Orgs don't have as cool an acronym as mine.........
