"Disowning" is both overly drasticizing and presenting in a far too black and white way what you are trying to achieve, and how you are trying to achieve it.
In very simple terms, you are trying to ensure a safe environment for your younger children (and yourselves). In his present state of development, your older son has demonstrated that his visiting your home is not consistent with that safety.
You are in no way disowning him or cutting him off,
instead you are making it clear that until he can take responsibility for his actions, your contact with him will be away from home and in places where there will be witnesses and repercussions if he abuses anyone.
I don't want to fuel a domestic, but what exactly does your wife propose doing if your son is in the house and begins to act like an arsehole?
A: say "that is nice" and pat him on the head?
B: completely deny that it is even happening?
C: call the cops and if they actually do show up that day, risk getting an armed [ster]roid raging thug, acting out in your house...
I'd say meet him at the mall, and if he can show he has grown out of it, you can start to carefully lessen the distance, on the other hand if he hasn't calmed down and taken on some adult responsibilities by the time he's about 25 years old, You'll likely have to face up to having a sociopathic (in the broader sense) son, and treat him accordingly.
