I just happened upon MensRights, and glanced around to see what the content is. It seems to be the case, but I hope:

-MR isn't some misguided counter-movement to women's rights.

-MR isn't acting on the assumption, or debatable hypothesis, that men are a marginalized group in the society of those who participate in MR advocacy.

-That MR is advocating for equality for all people; because, inequality of an individual based on an identity that they fit into is no grounds for placing them in a less than equal status.

MR can be a good or bad thing, just like women's rights, minorities right's, queers' rights, or any humans' right issue.
