Maybe feminists need to stop complaining about MRA's too?
You're making a false equivalency. Your argument here is akin to this:
Me: Homophobes should stop complaining about gay people.
You: Well, maybe gay people shouldn't complain about homophobes!
When feminists complain about men's rights advocates, it is because of things that men's rights advocates
actually do. Men's rights advocates actually argue that Western women are too slutty and un-feminine (read: they have minds of their own) and that mail-bride services are a great idea because foreign women know how to behave. Feminists think this is bad (for lots of reasons, particularly the sexist expectations of how women should behave to the often racist ideas about how women (particularly Asian women) are supposed to act), and criticize men's rights advocates who say it. Men's rights advocates argue against giving greater support for domestic abuse victims, and in doing so they lie about bills (claiming that they don't help men, when they do, or that they are actually misandrist, which they are not). Men's rights advocates claim that women often lie about domestic abuse in custody battles, which is one of the reasons why feminists don't have much sympathy for men's rights advocates who talk about this issue. Men's rights advocates also argue that women lie about rape a lot - the "had sex, regretted it the next morning and cried rape" story. One men's rights site maintains a website called Register-Her, where men can "register" women who have commited crimes against masculinity.
Does
every men's rights advocate do this? No, I wouldn't say that. Have I ever seen a men's rights website where seething misogyny, rape myths, and fantasies about violence towards women is not the norm? Nope, and I think I've been on all the major sites. Feminists think that misogyny is bad... so they criticize people who are misogynists. In short, feminists criticize men's rights advocates (and related manosphere communities such as pick-up artists (PUAs) or the Men Going Their Own Way (MGTOW) communities) because of things they actually say and do.
When men's rights advocates complain about feminism, they don't complain about things that feminists
actually do. They point to real (or imagined) problems that men face, and say, "This is all feminism's fault." This is not equivalent at all, and arguing that one side has no legitimate cause for complaint is not the same as arguing that the reverse is true.
That's pretty meaningless then. If the Patriarchy is everyone:
MRA: Men don't get fair treatment in the Family Courts.
Feminist: Oh, that's caused by "everyone". We fight against that.
He didn't say "Patriarchy is everyone"; he said that patriarchy is a social order. Yes, everyone [who lives in that society!] is a part of that social order, but that doesn't mean that every person is then equally responsible. We all have our spheres of influence, and it is possible for a person within their sphere of influence to work on not reinforcing patriarchal norms.
