I would add that the MRAs are very much of a piece with the protofascist right in a number of ways, including hearkening back to a mythical better time, wanting to "restore" that better time, a fondness for dominance and obedience, and an extraordinary ability to blame all their problems on "those people". The main difference seems to be that the MRAs want to blame women and feminists, whereas the protofacists tend to blame brown people and the left. In both cases, though, it seems to me to be about pushing for their dominance.
For those interested in the roots of MRA craziness, there's a great book called, "Why Does He Do That?" It's written by a guy who has run a program for abusive men for 15 years and is a great examination of the attitudes and behaviors that underlie abusive behavior. He doesn't mention the Internet in it at all, but over and over I was struck by the parallels between that and various aspects of Internet culture, including the MRAs and the anonymous trolls.
