Usage notes

  • In the United States, 'rainbow' groups/families/alliances/coalitions were originally those made up of several races or ethnicities. The term is now used more broadly, to refer (in the 2007 quotation, for example) to an alliance of several political parties. Separately, use of a rainbow flag as an LGBT symbol has led to the term being used to refer to LGBT groups (initiatives, etc).
