Perhaps most hideously, men through history have been subject to genocidal, or gendercidal, violence targeted at them specifically because they are men. Writers like Susan Brownmiller have over the last decades helped to show how mass rape and sexual violence against women are often a deliberate part of genocide; similarly, there has been increasing awareness in recent years of the gendercidal results of sex-selective abortion and infanticide in places like India and China. But the way gendercide can be directed against men is much less discussed. One of the worst recent examples of this was in the Balkans war, where, according to genocide researcher Adam Jones, " All of the largest atrocities... target[ed] males almost exclusively, and for the most part "battle-age" males. " Similarly, in Rwanda according to Judy El-Bushra (as quoted by Jones):
it was principally the men of the targeted populations who lost their lives or fled to other countries in fear. ... This targeting of men for slaughter was not confined to adults: boys were similarly decimated, raising the possibility that the demographic imbalance will continue for generations. Large numbers of women also lost their lives; however, mutilation and rape were the principal strategies used against women, and these did not necessarily result in death.
Many of these examples—particularly the points about custody inequities and conscription—are popular with men's rights activists. MRAs tend to deploy the arguments as evidence that men are oppressed by women and, especially, by feminists. Yet, what's striking about instances of sexism against men is how often the perpetrators are not women but other men. The gendercides in Serbia and Rwanda were committed against men, not by feminists, but by other men. Prison rape is, again, overwhelmingly committed by men against other men—with (often male) prison officials sitting by and shrugging. Conscription in the U.S. was implemented overwhelmingly by male civilian politicians and military authorities, not by women.
Even in cases where women clearly benefit from sexism, it's generally not the case that women, as a class, are the ones doing the discriminating. Neither alimony nor custody discussions are central to current feminist theory or current feminist pop cultural discussions. Thereis no ideological feminist commitment to either of these discussions in the way there is to, say, abortion rights, or workplace equity. On the contrary, the alimony and custody inequities we have at the moment seem mostly based, not on progressive feminism, but rather on the reactionary image of female domesticity that feminism has spent most of the last 60-odd years fighting against.
When men suffer from sexism, then, they do so in much the same way women do. That is, they suffer not because women rule the world and are targeting men, nor because feminism has somehow triumphed and brainwashed all of our elected officials (most of them still men) into ideological misandry. Rather, men suffer because of the same gender role stereotypes that hurt and restrict women—though men, being of a different gender, fall afoul of those stereotypes in different ways. Women are supposed to be passive and domestic and sexual—so their employment options and autonomy are restricted and they are fetishized and targeted for sexual assault and exploitation. Men are supposed to be active and violent—so their claims to domestic rights are denigrated and violence directed against them is shrugged off as natural or non-notable.
