verbal abuse, unlike other kinds of abuse, requires a participating partner, a living human being to play the victim role. When you fill that role you're rewarding the verbal abuser's behavior; the longer you keep that up, the stronger the habit will become. Finally, you need to understand that most chronic verbal abusers aren't sadistic monsters whose goal is to cause pain -- instead, they do verbal abuse to satisfy their need for human attention. They cause pain because they've learned that pain will _get_ attention; it's not their purpose. That doesn't excuse what they do, but it's important for it to be understood.
Verbal abuse, unlike any other kind of abuse, cannot be done alone. The verbal abuser's need is to get and hold the victim's attention, along with the emotional reactions that are evidence of the power to do so. That requires the victim's participation and it means that the targets of verbal abuse aren't helpless -- there are things they can do to defend themselves. This isn't "blaming the victim," it's _empowering_ the victim. Second: You can't help alcoholics by giving them drinks, but you can help verbal abusers by giving them attention.
