"In Sheep's Clothing

Most people would greatly benefit by learning how to spot tactics used by manipulative people. The following is one of the best summaries I have seen of such tactics:
 
Denial – This is when the aggressor refuses to admit that they've done something harmful or hurtful when they clearly have. It's a way they lie (to themselves as well as to others) about their aggressive intentions. This "Who... Me?" tactic is a way of "playing innocent," and invites the victim to feel unjustified in confronting the aggressor about the inappropriateness of a behavior.

Covert Intimidation – Aggressors frequently threaten their victims to keep them anxious, apprehensive and in a one-down position. Covert-aggressives intimidate their victims by making veiled (subtle, indirect or implied) threats. Guilt-tripping and shaming are two of the covert-aggressive's favourite weapons. Both are special intimidation tactics.

Guilt-tripping – One thing that aggressive personalities know well is that other types of persons have very different consciences than they do. Manipulators are often skilled at using what they know to be the greater conscientiousness of their victims as a means of keeping them in a self-doubting, anxious, and submissive position. The more conscientious the potential victim, the more effective guilt is as a weapon.

Shaming – This is the technique of using subtle sarcasm and put-downs as a means of increasing fear and self-doubt in others. Covert-aggressives use this tactic to make others feel inadequate or unworthy, and therefore, defer to them. It's an effective way to foster a continued sense of personal inadequacy in the weaker party, thereby allowing an aggressor to maintain a position of dominance.

Playing the Victim Role – This tactic involves portraying oneself as an innocent victim of circumstances or someone else's behavior in order to gain sympathy, evoke compassion and thereby get something from another. One thing that covert-aggressive personalities count on is the fact that less calloused and less hostile personalities usually can't stand to see anyone suffering. Therefore, the tactic is simple. Convince your victim you're suffering in some way, and they'll try to relieve your distress.

Vilifying the Victim – This tactic is frequently used in conjunction with the tactic of playing the victim role. The aggressor uses this tactic to make it appear he is only responding (i.e. defending himself against) aggression on the part of the victim. It enables the aggressor to better put the victim on the defensive.

Playing the Servant Role – Covert-aggressives use this tactic to cloak their self-serving agendas in the guise of service to a more noble cause. It's a common tactic but difficult to recognize. By pretending to be working hard on someone else's behalf, covert-aggressives conceal their own ambition, desire for power, and quest for a position of dominance over others.

One hallmark characteristic of covert-aggressive personalities is loudly professing subservience while fighting for dominance.

Projecting the blame (blaming others) – Aggressive personalities are always looking for a way to shift the blame for their aggressive behavior. Covert-aggressives are not only skilled at finding scapegoats, they're expert at doing so in subtle, hard to detect ways.
