Single mothers are unquestionably a pox on society, regardless of what reasons one might come up with to explain why they are here, so I am genuinely surprised to see so much damage control over it. The only person to blame for a single mother household is the woman, as ultimately all power over sex, pregnancy, and children lies with her. If she chooses to be a poor steward of that power, then she should be held accountable, even if I know such an idea is anathema to women and estrogen addled men.
The fix for single motherhood is also extremely simple, as it was invented before we invented writing, and likely even before we invented agriculture. This is a purposefully self inflicted issue that is perpetuated to fuel women's hedonism.
