The thing about projection which most people who use it fail to realise is that if one is the subject of another's false accusation, one can know with absolute certainty that it is untrue. Which offers massive insight into the person making the false accusation since you know that what they are accusing you of must come from within them - either what they would do or have done. Projection is so revealing of the person doing the projecting that I wonder why they do it. They may be able to fool onlookers but the person who is the object of their false accusations gets a second-to-none insight into their accuser.
