Basically, I agree with you. However, I'd add that slamming doors and throwing plates, while not directly abusive, is violent (probably engendering fear), and violence is a major warning sign. If I saw that level of violence in a marriage, I'd strongly recommend counseling, because it will escalate without intervention and repentance. It's a frighteningly small step from throwing a plate at a wall to throwing a punch at the perceived cause of one's distress.
By the way, if the plate is thrown at the spouse (even if it misses), that is abuse.
