Let's say there's a large group of people who are under a negative influence but are forced to keep quiet about the fact or they may face brutal consequences.
My idea comes from the book "Watership Down", when the humanized warren with which the main character "Fiver" envisions a horrid slaughter factor concerning that specific warren. When the warren is asked about it, the questioner is automatically shunned, or is interrupted by a sudden interjection. Is there a word for this type of behavior? What is paranoid reluctance to answer something because of superstition/unnatural concern?
Edit: Think of a situation in which you start questioning and are suddenly hushed, interrupted or interjected because someone doesn't want you thinking about that, or possibly bringing it up, and that specific reason is kept from the questioner. What is that action/attitude against somebody called?
I need it in the context of being of accusation. Like,
You're being [word].
And if there's a specific saying or reference referring to this action, I would like to know that as an alternative.
