Anyone that thinks men and women live equal lives, with equal risks and benefits really hasn't looked at any data. We've come faaar in the Western world. Beyond that it's pretty much disgraceful at best. Is there more terrain to gain, and differences between men and women to erase. Well, yes.
But to answer the thread, in theory, yes. A movement looking into the interests of men where it relates to guy issues would be a very good thing. There are certainly issues where men have received the short end of the stick, and could use attention too, in our striving for equality.
The problem I would see is that this won't become a movement dedicated to the same equality as one believes the feminist movement is and should be striving for, but that it would instead become an opposing force. A bastion of anti-feminists. Just turning it into a divisive gender war where lines are drawn, positions harden, and it becomes attack and defense, rather than society moving towards unity.
