I read book about Mohawk jokes with Catholic priest which Mohawk guide him every where in America and learned their religions each other which believe in same beliefs. Anyway Mohawks called non Indian American an "Injun" when not respecting each other tribes properties and people so this has been around since Revolutionary time and until later same radical slur occurred to black "N" word so anything happens to civil unrest against America that always done by calling names because "its not who you are or on my side" during civil war.
