There are lots of good reasons to talk about issues affecting men, but sadly the bad parts of the MRM far outweigh the good at this point. I'd say it's 85% bashing feminism, complaining about women's sexual power (e.g. The Friendzone), denying and minimizing rape as a social problem, etc. and only 15% talking about fathers' custody rights and boys' education issues.
