They were shoving food in the mouth of a child that was screaming that they don't want it? Yikes. That's abusive and will cause eating issues. I had some issue when I was little that I just wouldn't eat and my mother abusively screamed at me until I'd get hysterically crying and run away from the table to hide in my room. It was horrible and abusive and I did/do have eating issues.

When my kids didn't want to eat, I never forced them. I'd ask them to just try a taste of the food, but if they wouldn't even do that, I'd just not say anything, but not let them have any junk food until they ate something healthy when they were ready.
