STEREOTYPER

Its not really the discourse or the topic, its the choice of example. If there is a pattern of chosing examples from the same pool of source, its called stereotyping or typecasting. 

The topic is racism, ok. But if the examples of racism are pointed at just one particular race, or group, or label, or any form of identification, as if there are none other examples, that can b detrimental and poisonous. 

Beware of such writers with a set victim to b stereotyped or typecasted.
