I see Azizi's intention in starting this thread as a means passing on information about what might be considered offensive to some people in some situations, from her perspective. The particulars of that she has--and will further--elaborate on. That's valuable. More knowledge is a good thing.
What you do with that knowledge is up to you. She's not telling you how to speak... she's just informing you of the ways your speech might insult. You can never make the assumption that others always possess that knowledge already.

So if you want to racially insult African-Americans, you now have a few tips.   ;)
