Just a general comment or response to the OP.
In all fairness, there is a bit of a double standard here. That is, women and men have different levels of resources and support. For example:
Woman sometimes find themselves at an impasse in life:
Woman gets courted and treated like a princess. Guy tells her he’ll take care of her for life. Ten years later, she has a passle of little kids, and hubby is never home: He’s out fooling around with other women. Woman has no job skills, and she fears that she’s never going to get enough from hubby in a divorce settlement to pay for the kids’ upbringing and help her get set up to support herself as well.
Answer for such a woman: Feminism and its related organizations and resources. Feminism tells her to have confidence in herself, directs her toward resources for getting an equitable settlement in court, etc.
Meantime, men can also sometimes find themselves at an impasse in life:
Man courts a woman and treats her like a princess. He says he’ll take care of her for life. Ten years later, and she has turned into an unbearable harpy. If he tries to stand up for himself or argue with her, she cries, “Spouse abuse!” If he wants to go to a counselor or talks about a trial separation, she promises that she’ll rape him in court. Meantime, at work, he knows he can be fired, expelled or arrested based more or less on the word of any woman. He knows he is basically guilty until proven innocent in most situations.
Answer for such a man: None. Any organization that might pop up to help him boost his confidence or give him resources would automatically be branded misogynist and neanderthal. The assumption is that guys are supposed to figure this out for themselves. Or they’re supposed to be more like women. Or something.
Summary:
I think the real answer is that both women and men shouldn’t let themselves get in these fixes in the first place. That is, men and women should have enough self-confidence and presence of mind that they should be able to handle life without needing organizations and laws to help them: “Just stand up for yourself!”
But experience proves that both sexes can get themselves in jams. Not all men or women get themselves in such gams. But some men or women do.
Trouble is that it seems men aren’t allowed to have the same fall-back resources as women. In fact, feminists even argue that feminists are working for men as well. So men shouldn’t need male-oriented organizations; they should just become good feminists.
Right…
Anyway, I’m not a member of an MGTOW or MRA group. I haven’t even checked out their websites beyond what was linked in the OP. (And I did laugh at the posters.)
Still I register the lopsidedness of things sometimes. That is, men aren’t supposed to have or need their own public organizations: The argument is that traditionally men already have things like golf clubs and “old boy networks” that serve as pre-existing support networks for them. Trouble is, not all guys have access to those old-school resources. And without access to those things, there aren’t really any centralized networks or hubs to give guys guidance that some may need.
So as a result, you get guys ranting on the Internet about mistreatment by women; a lot of it is borderline misogynist. So maybe some more "official* men’s group with a more positive slant might help out.
Again, not all men would need this help. But some men might.
(Just brainstorming here.)
