Consider the following:
A individual of BLUE ethnicity is down and out on his luck. He decides to rob a 7-11. He successfully makes off with $500.
The local newspaper writes an article about the incident, and of course the online commenters come out in force:
Billy Hick Jr writes: And this is news why? BLUE's always do this.
Sam K agrees: typical behavior of BLUE's.
Does this individual really reflect back on the group? The answer is no. The answer is yes if you are stereotyping.
