Yes, and she was deliberately brutal, choosing her weapons and targeting her blows to maximize their impact against my medical problems. She did it when she was frustrated with her own life, mad at me for not meeting her narcissistic needs, and for independent thinking. Granted, I was also a PIA kid with an attitude, but 95% of that was due to her being a sick individual in a sick cult.
She does not justify herself at all now. She does not believe it needs justifying. The borg said your kid would not die if you beat her, and I didn't die, so their truth is proven (in her warped mind). Not only was she told I wouldn't die, but she was commanded to beat me.
Yes, the talks from the platform characterized children as bulls that needed to be bridled and beaten into submission--there is no other way to teach children.
Once I tried reading her the scriptures about exasperating your children (can't remember the exact quote right now), and well, you can guess how she reacted.
There was some publication in the 80s that said parents needed to wean themselves off the beatings as a child aged and learned how to control herself. I read that to her as well, but she said I wasn't ready for that. On my high school graduation day, she was embarrassed to have refused to give me a gift or celebrate it, and tried taking that out on me (as she did with any of her personal frustrations). I held her arms back and informed her she would never hit me again. And she didn't.
