MRAs do exist and many of them have been addressed by the Southern Poverty Law Center:
"Misogyny: The Sites
The so-called ?manosphere? is peopled with hundreds of websites, blogs and forums dedicated to savaging feminists in particular and women, very typically American women, in general. Although some of the sites make an attempt at civility and try to back their arguments with facts, they are almost all thick with misogynistic attacks that can be astounding for the guttural hatred they express. What follows are brief descriptions of a dozen of these sites. Another resource is the Man Boobz website (manboobz.com), a humorous pro-feminist blog (its tagline is ?Misogyny: I Mock It?) that keeps a close eye on these and many other woman-hating sites."

"The Southern Poverty Law Center monitors hate groups and other extremists throughout the United States and exposes their activities to law enforcement agencies, the media and the public. We publish our investigative findings online, on our Hatewatch blog, and in the Intelligence Report, our award-winning quarterly journal."

From what I gathered they aren't much different (if any different at all) from feminists, some of them have a pretty good point (women recieve more child custody, less jail time etc.) but has a lot of crazy offshoots with idiots saying idiotic things (again, like feminism). The main difference is that while current media tells you that (current)feminism is good and the fanatics don't represent the majority, it treats MRA like the second coming of mecha Stalin and Hitler and highlighting the fringe groups as the norm rather than the exception.
Actually they are completely different from feminsism. Mainstream MRA's, have been addressed by the Southern Poverty Law Center for Misogyny, vs mainstream feminism does not support Misandry.
