Kerry Edwards need to explain to the public, the concept of projection - attacking an opponent by projecting your own weaknesses or failures on to them.
We learned this in Psych 101 people.Projective Identification (anger / Lever 1)
"This can be related to pushing the treater’s ‘buttons’. After a client is able to find the treater's weak spots (a countertransference hook), the client can then push a treater’s buttons as a way to gain control over the treater."
