Men do face many challenges. Some men have dangerous jobs which they die providing for society (fishing, war, etc). This doesn't get enough acknowledgement. But one doesn't have to be a total jerk to make this point and tear others down.
?? Are you implying that feminism is limited to just helping women? Surely you're not that naive. If we were to play a game where each time you post a crazy thing an MRA has said, I have to post two crazy things feminists have said, I'll win that game. I'll win it easily. I'll win it with politicians and academics and people who have real power in our society while you'll be scouring fringe websites. And if ever I run low on important people, I still have the Tumblr feminists.
So yeah, I don't really know what point you thought you were making, unless the point was to demonstrate the totally different standard that you hold these groups to.
If you think feminism has legitimacy (and it most certainly does) it's because you're choosing to listen to the points that have merit, and disregard those that don't. It's selection bias, sure, but I do it too.
Consider trying the same thing with three MRM
On the other hand, when looking at the MRA scene (again, going by self-identification of the speakers), the mainstream seems to consist of "incels", red pillers, and the like. So, as far as most people are concerned, the label is firmly associated with that sort of stuff. Consequently, suggestion to listen to "points that have merit", when they come in a binder with "MRA" on the cover, is not going to fly. If you want to be heard, you'll have to break the association by using a different label - or by finding enough like-minded vocal associates to reclaim the label (and at this point it would need to be a supermajority with a hefty margin before we can seriously start talking about this).
You might object that this is unfair, because the label is descriptive and appropriate, and all those misogynists have misappropriated it. Tough luck - descriptive labels get misappropriated all the time. For example, if you happen to be a socialist and a civic nationalist at the same time, a common sense descriptive label would be "national socialist" - but you really shouldn't be using it for obvious reasons.
I've associated feminism with "women make $0.67 for every dollar that a man makes for the same job, working the same hours" and equal gender ratio over equal opportunity.
The negation of "attacking women" isn't "supporting women", it's "not attacking women". Not saying anything at all about women is "not attacking women", but it's not "supporting women".
