Why didn't the parents get mad at Uncle Frank for calling Kevin a little jerk?

"And the parents were paying for Frank's vacation and the pizza. I would have slapped Frank and left him HOME ALONE."
Kevin left alone with Uncle Frank. That wouldn't turn out well.

At first I thought it was Peter who said "Look what you did you little JERK" in Kevin's flashback, I agree the way it was said in the flashback scene was a lot more cruel, I also don't get why we never saw what Buzz told him earlier in the movie.

My sister and I used to always reenact those flashbacks. Every character that shows up is exaggerated and say things far more obnoxiously than they actually said it. And Buzz just randomly talks about feeding Kevin to his spider which did not happen at the start of the movie (although it could very well have been something he said at some other point in time).

Well we remember things differently so I thought it was clever of the director to do that.

I had never put 2 and 2 together with the mom’s tone and I’ve seen this movie a million times. I like how the movie crammed so many family dynamics into so little time.

It's unfair to us, but this film is really for kids, where **everything** is unfair as far as they're concerned!! I love the part in Christmas Story where Ralph fantasizes about his parent's horrified reaction and guilt to his blindness due to soap poisoning.

I don't consider what Frank did to be discipline. He just insulted the kid with no real punishment. Additionally, the child's parents are in the room so it's best just to let them handle the situation.

This is back when other grown ups were allowed to discipline children and humanity was better for it. Whether you think Uncle Frank was a jerk or not he was an authority figure to all those kids and disciplining an authority figure for shaming a kid for his bad actions undermines his authority tears apart the family.

If a kid does something bad and you berate the adult punishing him and baby the kid you get a country like we have now

I disagree, CoachGainz. Frank is definitely the biggest jerk in the movie. Kevin's entire family are jerks, but Frank is the worst. I understand being frustrated because the dinner was ruined, but he had no right to call him a little jerk. He could've easily just said, "Look what you did!" But calling him a little jerk was way out of line.
