"Silencing is an extremely effective tool for creating fear through subtle controlling behavior. With such a dramatic imbalance between the marginalized and those with power, it’s also a pervasive one. These techniques often encourage others of all power levels to engage in policing, to help maintain the dominant class. It’s analogous to the popular kids in high school protecting each other to preserve the social order, the kids who hope they’ll one day be popular joining in, and those that don’t want to be singled out sacrificing each other to avoid being targeted."
