I don't think there'll ever be reasoned, unbiased debate about the MRAs here. It just ends up in "they don't need a movement" or "feminism fights for men too, they're redundant" which is blinkered and self-congratulatory.
If you actually do something as ridiculous as asking men about their views on "men's rights" (e.g. here or here) you find that they do have genuine concerns that feminism isn't addressing in a meaningful way. I'll put out some quotes for the people who don't want to follow the links, which are SFW by the way.
"I think that they bring up some good points just as general feminists bring up some good points. My problem is generally that people take things WAY too far."
"I like the idea of equality. I feel there are certain issues (custody, alimony, he-said/she-said violence disputes, societal condemnation of pre-convected/un-convected accused of sexual crimes, etc) that are unfair towards men. I feel that feminism doesn't seem to address these issues with any type of priority. I do NOT agree with the more extremists of either group, feminists or men's rights activists."
"I think men's issues are by and large ignored by the groups that say they address them, so the men's rights movement is the natural response. Some of what I see on subreddits and blogs related to it can be ridiculous, but a large amount is worthwhile and on point. As with anything the radicals are ridiculous and the moderates are fine. I would prefer if a men's rights movement wasn't necessary, but the other "right's" movements aren't egalitarian, so needs must."
"I'm both a feminist and a men's rights advocate. There are some really strong parallels in both. In both cases, there are completely legitimate grievances that are even now ignored. In both cases, there are real injustices going on that have no place happening. However, in both cases, people see a movement for one gender as the movement against the other. I've been strongly against such people on both fronts I don't like feminists who use the name to slander men, and I don't like Men's rights advocates who use the name to slander women. This isn't rocket science We all deserve a shot at equality, and we all deserve to be heard where equality isn't how things are. We should all be working together towards making things more like how they should be in general, rather than wasting our energy on stupid fights between people who fundamentally agree."
"They're certainly not perfect, but they fulfill a very important role. Feminism is a woman's movement, not some all-inclusive movement for gender equality. They have neither the will nor the ability to address men's issues, except in the very narrow ways that men's issues can be interpreted to be side-effects of women's issues . And it's really not a problem that feminism doesn't address men's issues—they're perfectly free to focus their efforts on what they have a passion for. But what it does mean is that we need a men's movement too, because as it is, the modern discourse on gender issues is almost entirely dominated by the women's movement and as a result, men's issues get almost no attention at all (despite the fact that the issues men face really aren't all that trivial). There's nothing wrong with there being a woman's movement, but there is something wrong with there being a woman's movement without a men's movement to challenge it and provide a counter-balance (I wouldn't want a men's movement without a women's movement either). As for the actual issues I take with the men's rights movement, they spend too much time attacking feminists themselves instead of rationally challenging their ideas and providing the counter-balance that I talk about. It's very important to look at feminist ideas and challenge the ones that don't make sense, but there are too many people in the men's rights movement who make the jump from "I disagree with feminists" to "feminists are bad people". I fully believe that most feminists are well-meaning, whether I agree with them on certain issues or not."
