This is normal for brats. SJWs are brats and Jazz is the ultimate brat. He's getting better now, but he was one during most of the filming.
I work with kids and he's not bratty compared to most I work with. I mean, North American kids are infamous brats there I said it it's true I know it you know it. Jazz is pretty mild.
In fact, I see traits of him being a pathological people pleaser, like many child performers are. So when he did act bratty I can only imagine his mother and other adults had driven him up the wall beforehand. I've seen some shitty moms just like Jeanette needle and poke, needle and poke and then act exasperated. Poor mom, she has such a difficult child! Isn't he crazy?
I don't tolerate much shit from my kids but I don't go out of my way to drive them insane the way Jeanette does. Here's the way Jeanette usually does it, especially with Jazz.
Jeanette: What shoes are you going to wear?
Jazz: These shoes.
Jeanette: NO.
It's maddening. She does it all the time. She asks a question, gets an answer, makes a rage face and says "NO!!!!" I mean, if she has a pair of shoes in mind, why doesn't she just say "Hey, Jazz, those shoes will look bad on camera. I think those sandals will work best with that dress, you want me to grab them?" It's not her business what fucking shoes he wears, really. But if the shoes were that important to her, that's what she would do. It's about the fight, though. She asks a question, knowing that her kid will get it wrong, then acts like he is insulting her.
People like that drive others around the twist.
A friend got her own mother to stop that (kinda) by getting really confrontational with her. I grew up with her and saw her mom in action. My friend told her she was always bitching about her own mom doing that. She told her she was a vicious, unlikeable person. But it also took marathon screaming matches where *my friend* looked like a rage-oholic. Her mom got to tell her friends what is was like to have a honey badger for a daughter. But basically my friend just had to build more stamina than her and wear her out. If her mom tried those little abuser techniques, my friend had to make sure she got no payoff and only suffering. She noticed that the longer the period between the offense and forgiveness, the less often her mom did that. If she forgave too soon her mom would try again quickly. Basically, my friend just went full aversion-therapy. Don't let any namby-pamby New Age whiney pop psychologist tell you it doesn't work. Her mom learned treating her like shit = hours of anxiety and misery. Every time. No one likes feeling anxious and miserable. There was no sadistic satisfaction anymore.
Now my friend can tell her that she's starting to set her off, and her mom will usually retreat.
Jazz forgives very quickly. He thinks he got Jeanette and his siblings to back off, but really they're just redirecting him so they can continue in a few minutes. Sander, effete prick that he is, does this the most. Jazz needs to leave that house and not go back, but if he's going to interact with his family members I would suggest long gaps of time between the offense and forgiveness.
I strongly recommend living in a trailer somewhere before EVER going back to Florida. Limit contact to the phone. Grey rock and then make them all wait hours, days, weeks, even months before talking to them again. They'll melt down and have tantrums like you've never seen. They'll cry to the point of sobbing. Stay icy. In fact, mock them a little when they're crying, telling them you know this is manipulation. Abusers don't like being viewed as a joke. Trust me, they'll clean up their behavior after a while.
And if any Kiwis here are going through something similar, trust me, it works. Abusers are cowards and count on you having less stamina than they do. Grey Rock combined with ridicule.
