But we're not talking about mental handicap here. We're talking about normal functioning people who make stupid decisions. I don't think genetics has anything at all to do with that and I've never seen anything that would make me believe it does. Given that, the only negative influence such people have by breeding is the influence they wield over their children (which can be a lot, but can also be overcome).
