Partly why: They don't create life and give birth. That, coupled with an inability to develop empathy can be some dangerous ingredients.
Now,
- could it be that men are over-represented on the both ends of the spectrum(s)? Genius - Retard? Empathic - Cold blooded murderer? and so on...
- how much funding do men related healthcare programs get? ie: "Obamacare" goes to great lengths to avoid mentioning "men" at all
- how many mass shooter men were being raised by a single mother? How does the lack of a father affect a boy?
- how does the increased age of a woman giving birth affect the mental health of a child?
Not enough of us spend enough time developing it, while the wonderful women in our world often have a headstart, quite often due to Men to begin with, lol.
I think the points you're speaking to might be better addressed by our fairer gender. :)
