That's interesting that people felt it worth the time to email.
I think what's going on here is that some people (myself included) find it extraordinarily offensive to question someone's right to procreate, whether they're "good enough" by some metric to have done so. Are you young enough, rich enough, smart enough, tall enough, moral enough, etc.
Of course, the offense can be a combination of being offended on behalf (of Mitnick in this case), and also projecting (what if we lived in a world where people questioned whether I should have children for reasons of age, wealth ... or worse reasons.)
I think we live in a world where we need all kinds of people from all kinds of parents; when we start to pick at who "should" have children, we risk losing something.
