Rev Eliezer, I find your blanket statement “abused parents WILL abuse children” incredibly offensive, untrue and frankly disgusting. Every human being has a choice, a bechira. One of the foundations of Yiddishkeit is the knowledge of the fact that humans control their behaviors. There are wonderful parents (and adults) who were abused as children and there are abusive parents (and adults) who had wonderful parents. Stop perpetuating a lie. You are essentially saying that all victims of abuse are or will be abusers and that is a disgusting and totally untrue thing to say.
It is realistic to say that oftentimes abusers were victims of abuse themselves but it is not a guarantee that all, or even most, victims of abuse will become abusers themselves.
