I (20M) am researching both Feminism and MRA movements to get an idea of what both stand for. Based on a cursory search, both are fighting for the rights of their own genders. So here is my question: why is it so hard to band together?

I have unfortunately seen a lot more hostility towards MRAs than Feminists, but that does not mean that Feminists do not receive hostility (far from it). Based on my personal, unscientific observations, I am curious as to why Feminists and MRAs despise each other. In my mind, fighting for women's rights is not misandrist and fighting for men's rights is not misogynistic, but they seem to be perceived as such. My post was auto-modded over at r/Feminism , so I wonder if the same thing will happen over here.

Edit: It was not auto-modded. Curious, curious indeed.
