Cherry picking incidents involving the actions of disturbed individuals to attempt to smear a multifaceted movement is intellectually dishonest. That's like claiming all Muslims are terrorists because some Muslims are.
That is not to say there there is no benefit to considering the rights of men or the problems that men face with issues like violent attack or custody disputes.
"Disturbed individuals"? Did you read the articles? The people being describes are the leaders of the "movement", like Elam. The "movement" obviously encourages the behavior being described -- meanwhile, groups like CAIR work hard to address the popular image of the terrorist Muslim. Where is the CAIR of "men's rights" I wonder
There are some Muslim leaders that express disturbing things as well. Once again, this does not make them the voice of mainstream Islam. If you actually visit a large men's rights community, like http://reddit.com/r/mensrights, you'll find that some women participate in discussion as well and the men are not the rape-happy bugaboos that many paint MRAs in general to be.
Mainstream segments of the movement, if you will. The mainstream of any movement is where a sense of tribal identity emerges that's likely to engage in partisan disparagement of other movements seen as opposition.
