That just tells us the person wasn’t a good parent either. Your comment assumes the only way to parent is to manipulate, patronize, etc. That’s just one perspective though.

There are other ways to parent that are actually fantastic management training - figuring out how to think from another human’s POV, acknowledge their frustrations, help them build the skills to handle their feelings, etc.

It turns out great parenting is to a first degree about great relationship skills.
