I don't think that's what the original poster means. I think (s?)he means that the loud group of people with idealistic beliefs seek out examples of people, that the average person can relate to, to serve as examples of their ideals i.e. Joe Teenager contracting HIV from his immoral behavior. I'm sure all these people are nice when you meet them, as most people tend to be, and would never wish anyone personally to contract a disease, but they love malleable statistics and impressionable stories to support their positions.
