The caliber of people who believe it is lacking. Also lacking is both common sense and working brain cells numbers. But the ones I know who think that way are disgruntled with their own lives and choices and would rather convince themselves that it's always someone else's fault than admit to their own failings.

We share a son. luckily, him being a crappy Dad has kept our son from falling into the wormhole.
