Because anything that results in males getting more sympathetic attention than them for any reason must be intrinsically unfair. They do the same thing with suicide. Some of them say that male suicides are good, actually, because it's just manbabies who are butthurt that women are equal to them now and can't cope. Others say that suicide isn't that big an issue because women have way more important issues, like not getting free tampons, or Jew day care not paying as much as a real job. I don't know of any feminists who say this when it's their son, husband, or father who commits suicide, FWIW.
