This picture is a perfect representation of the stereotypes that every people of coloured experience probably in their daily lives. Stereotypes such as people with colour are known for stealing things, this is why it is important to keep an eye for them when in stores. No stereotypes for any race should exist. People choose to act the way they do, this has nothing to do with their race. Stealing, killing, etc. are done by everyone, not just stereotypically by black people/people of colour.
The Black Power fist is a logo associated with black nationalism and sometimes socialism. Its most known to be used by the Black Panther Party in the 1960s. A black fist logo was also adopted by the northern soul music subculture.
