Therapy would definitely be a good start.

Man this is why I absolutely do not want sons. I think at some point I'd be willing to kick one out for this shit - sons can represent a real danger to their mothers, especially if they have uncontrolled anger issues like this.

Therapy doesn't help with this. Lundy Bancroft states that only programs designed to combat abuse specifically have any chance of working, because they address the deeper (misogynist) thought patterns that fuel abuse, which therapy doesn't. Therapy exists to help the patient deal with their own emotions, but it largely doesn't pass judgment or "intervene". Anger is not the cause of abuse. It's just the outlet.

He needs discipline and to be worked HARD by people who aren't his mother.

Anger management classes/therapy would be absoluty necessary. These traits are often passed from parent to a child, can manifest at any age even is that parent isn't present in their life, and need an early intervention.

She needs to confront him about his behavior and provide some type of repercussion. His attitude is not okay at all. She should not live in fear in her own home.

Many teenage boys are on some type of power trip. And Yes, I said it! They try to instill fear in women and young girls because they think that is what it means to have power. They rarely try that with grown-ass men or boys their age.

Ex:

One time when I was covering a classroom and a teenage boy tried to fight me!?!? Girrrrl.

He was one of those upper-middle-class kids who wanted to act like they were about that life. You know the type🥴.

Now what got him riled up you may ask?

I had asked him to sit down multiple times and he proceeded to charge at me. He thought because I was small I would just take it. I didn't move or flinch. I didn't instigate. I took up space and stood my ground. Inside I was scared af lol, but I was not gonna let him know that.

It shook him. He was used to pulling these types of stunts with female family members (or so I'm told), which worked in his favor. He learned that day he can not instill fear in others as he does in his household. In real life people have choices and they won't sit there and take his behavior.

I would give him up for adoption.

So sad. Poor woman went through hell with an abusive spouse and now has to put up with more abuse from her kid. Better days, won’t you come?

If I were dumb enough to have a male child I would hope I would be witty enough to put him up for adoption if he were to ever show aggression like this. Male aggression isn't just socialization- it is also genetic.
