Saying that they make good people easy to fleece is itself a fallacy. First it starts by impressing onto oneself that they are only good and inherently not bad which leaves them deluded into thinking that they can only do good, think good and be good. A deluded individual is not a good individual, good people are easy or easier to fleece than an individual that realizes their capacity to be indifferent as much as their capacity for altruism, it's deluded people that are easy to fleece because their behavior and the thinking which drives their actions is one dimensional and easy to predict. After you have deluded individuals into this "one dimensional cannot err belief" then you only need to con-vince them that what they need to do is good.
