You know, my dad tried to commit suicide, a few years after his twin brother did. In both cases it was because they had a flawed grasp of reality, their perception of events was distorted.
Any case of parents killing their kids who they love, and themselves, and even some where they don't kill themselves, seems to have a similar origin. Somehow they come to believe things would be better for their loved ones with all of them dead. Maybe the kids won't be able to cope without the parent, maybe they will be targeted, maybe they are infested by demons, whatever. Not rational thinking. That's what happens in mental illness.
I find it really shocking that anyone, whatever their sex, where all the evidence is that there is something like this going on, becomes generalised to some sort of political drum. Or that there is a complete denial that men suffer from mental illness that cause them to behave abnormally. Because that is what threads like this read like.
