Remember the only qualification to become a parent is functional gonads. No education, training, or proof of competency and aptitude is required.

Which is why shit parents often resort to physically assaulting their children. It's because the are too ignorant of actual parenting techniques and methods to know otherwise.

"My parents spanked me and I turned out fine"...

No you fucking idiot, you did not turn out fine. You are beating a helpless child because you don't know shit about parenting.
