It's understandable (and regrettable) that there are people with academic dishonesty on their records. What I find disgusting is the number of people telling themselves that when AMCAS clearly asks if they've ever committed academic dishonesty, the posters then flock to SDN to seek someone to tell them that they don't really have to report it, or ask for ways that they could cover up the truth (aka lying).
People make mistakes. But mistakes have consequences, and adults learn to deal with those consequences.
It comes from a lack of reality: for example, the majority of Americans DO NOT cheat on their taxes, but when surveyed, people who have committed tax fraud believe that a vast majority DO.
The violent reaction we're seeing from these posters is their reaction to being confronted with the cold, hard, reality of life.
