These mostly may come from other men, these may mostly not be direct, and these may mostly be women not being eligible for this stuff (eg women not being eligible to be drafted into wars in most countries) but misandry does exist.

Men are 9x more likely to be the victim of a violent crime Men are by far more likely to develop an alcohol or drug addiction Men get drafted into wars in most countries Men make up 3/4 of the suicides Men make up by far the most workplace fatalities And also the vast majority of people in power were men but only a really small minority of men have had power. And women have contributed to mens problems a bit more than it's made out to be. I've heard women make fun of men for being feminine more than it's made out to be.

And men also go through biological stuff: men have much weaker immune systems on average, and have drastically weaker parts that can feel weird if sat down on wrong.
