Instead of linking to wikipedia, I will post the text on there before the SJWs change it to fit their narrative about how cis males are the only ones who use it.

The Master suppression techniques is a framework articulated in 1945 by the Norwegian psychologist and philosopher Ingjald Nissen.[1] These techniques identified by Nissen are ways to indirectly suppress and humiliate opponents. In the late 1970s the framework was popularized by Norwegian social psychologist Berit Ås,[2] who reduced Nissen's original nine means to five. Master suppression techniques are defined as strategies of social manipulation by which a dominant group maintains such a position in a (established or unexposed) hierarchy. They are very prominent in Scandinavian scholarly and public debate, where the expression is also used to refer to types of social manipulation not part of Ås's framework.[3] Master suppression techniques are sometimes called domination techniques.[4]

Ridicule[edit] See also: Appeal to ridicule In a manipulative way to portray the arguments of, or their opponents themselves, in a ridiculing fashion.

Example:

Another speaker laughs at your accent and compares you to a character in a humorous TV show (although you had something important to say). When making an accusation of wrongdoing against someone, you are being told that you look cute when you're angry.

Withhold information To exclude a person from the decision making process, or knowingly not forwarding information so as to make the person less able to make an informed choice.

Examples:

Your colleagues have a meeting that concerns you, without inviting you. Decisions are made not in a conference where everyone is present, but at a dinner party later in the evening, where only some attendants have been invited.

Double bind See also: Double bind To punish or otherwise belittle the actions of a person, regardless of how they act.

Examples:

When you do your work tasks thoroughly, you receive complaints for being too slow. When you do them efficiently, you're critiqued for being sloppy.

Heap blame/put to shame To embarrass someone, or to insinuate that they are themselves to blame for their position.

Example:

You inform your manager that you are being slandered, but are told it is your fault since you dress provocatively.

Objectifying See also: Objectification To discuss the appearance of one or several persons in a situation where it is irrelevant.

Force/threat of force To threaten with or use one's physical strength towards one or several persons.

Example:

"One more word from you and I'll smash your face!"

Making invisible To silence or otherwise marginalize persons in opposition by ignoring them.

Examples:

Another speaker takes something you have said as if it was an idea of their own, or starts speaking despite it being your turn. As it is your turn to speak, the other attendees start to talk to each other, browse through their papers, etc.
