Racism

Racism is generally defined as actions, practices, or beliefs that reflect the racial worldview: the ideology that humans are divided into separate and exclusive biological entities called "races". This ideology entails the belief that members of a race share a set of characteristic traits, abilities, or qualities, that traits of personality, intellect, morality, and other cultural behavioral characteristics are inherited, and that this inheritance means that races can be ranked as innately superior or inferior to others.

Empath: The Luckiest Smurf stories
In the EMPATH: The Luckiest Smurf story series, racism exists between the Smurfs and the Psyches. The Psyches view the Smurfs (identified as Species 0002) as a savage race of perverts, which leads to their isolationism from other races, and to some extent how Empath was treated by the Psyches when he was raised among them. The Smurfs in turn see the Psyches as emotionless drones, with Papa Smurf being very reluctant to allow Polaris Psyche to have asylum in the Smurf Village because his son was taken by the Psyche Master and programmed with their particular racist mindset of the Smurfs. However, Empath's and Polaris' treatment from the Smurfs is based more on the fact that they are both telepaths, with Hefty being the most militant against telepaths in general because telepathy is one weapon that he has no natural defense against.
