My comment was intended in a general way. I know some cultures have particular ways of using language. With African American, it's "ebonics", and with Native Americans I suspect it is more a focus on oral than written communication since our culture had no written language until quite recently. Sequoia gave the Cherokee their first written language I think it was sometime in the 1800's, so I'm not surprised "AmerIndians" may have trouble with written language at times. I'm personally Cherokee/Caucasion mixed.
Thanks for pointing that out. It's an important factor when you have a unique culture involved in helping one improve their writing without it coming across as a cultural insult.
