You cannot just decided that you are going to define something the way you wish.Most likely those persons are bigots.The definition requires that one be in a position to evelate ones race. You cannot just dimiss facts. The US Supreme Court but for a brief period in its history the Warren Court was a racists institution. the Us Constitution was a racists document not because I say so but because those writers of it expressed and wrote those views themselves.There were numbers of free African Americans at the time of the Revolutionary War.Large numbers did not fight with the colonists because the declaration offered them no opportunity to be a citizen. Crispus Attucks and many like him just happened to be in the wrong place at the wrong time,not because I say it because I was not there but the history recorded by the Americans but not necessarily published in their mythology shows it. Thousands of free negroes and slaves fought with the British against the Americans because the Brits promised them freedom and citizenship.
