For decades in the U.S., there have been isolated incidents of removal of Confederate monuments and memorials, although generally opposed in public opinion polls, and several U.S. States have passed laws over 115 years to hinder or prohibit further removals.
In the wake of the Charleston church shooting in June 2015, several municipalities in the United States removed monuments and memorials on public property dedicated to the Confederate States of America. The momentum accelerated in August 2017 after the Unite the Right rally in Charlottesville, Virginia.[1][2][3] The removals were driven by the belief that the monuments glorify white supremacy and memorialize a government whose founding principle was the perpetuation and expansion of slavery.[4][5][6][7][8] Many of those who object to the removals, like President Trump, claim that the artifacts are part of the cultural heritage of the United States.[9]
Mary and Paul made a great deal of money recently by winning the lottery. They come from families of little education or money. They moved to a beautiful new home in a neighborhood well known for the wealth and high social status of its residents. The neighbors have been unfriendly to them, ignore their attempts to make friends, and talk badly to each other about the new family in the neighborhood. This is an example of <u>relational </u>aggression.
In the field of sociology, such a type of aggression that targets the social relationships pr status of a person rather than physically hurting him is referred to as relational aggression.
Relational aggression occurs when a person does not believe the other person to belong to his social status.
