Sticks and stones can break your bones, but words can do more permanent damage. Stockholm syndrome, being groomed, being broken down and molded, these are all this that can be achieved by words alone. Maybe Sarah took these things to heart and was incompatible with that environment, and it's healthy for her to express that. Nobody is expecting everything to change over one individual but she is not out of line in speaking her mind.
"Stockholm syndrome", "being groomed", "broken down and molded" - not just words. ALL of your examples involve more than just words - they are using words as part of a system of violence characterized by some form of imprisonment or threat of violence (assault). They don't work on people that can just walk away, or have access to other, neutral actors or supportive people. That is, they work only for people FORCEFULLY isolated or kept under constant surveillance.
So, you've just given us examples of actual, physical force and/or violence, where words are also used to emotionally and psychologically harm the victim. That's not what we're talking about, here.
