Thanks for the link. Yes, that does give pause for thought:

For example: once, when I was eight years old, I’d done something wrong that warranted a spanking. My dad commanded me ‘come here.’ I hesitated, building up my willpower, before complying. He spanked me and let me go as I sobbed. He then said “You hesitated. That’s disobedience - come here to get another one.”

At this point I was in a lot of pain, and the effort it took to voluntarily subject myself to another one was now way more. It took me a few moments before I could force myself to approach again. He spanked me again, let me go, and as I sobbed, he told me again that I had hesitated, that this was disobedience, and that it warranted another.

By this point I was in even more pain, and it took even greater effort to overcome my body’s desire to flee or fight. And so again, there was a few second delay. And so he did it again.

He did again eleven times. And when he told me the twelfth time to approach, something in me completely broke. It didn’t matter that my body was now in overwhelming agony - possibly the greatest pain I’ve experienced in my life - the only way to make it stop was to abandon my will entirely, to become a mindless obedience creature that would walk straight into the fire instantly when commanded. So I did, he spanked me one last time, and then he stopped.
