I really don't know how to answer the question any different than I did. One's own personal testimony IS legally sufficient to prove a case for racial harassment. I thought that is what I explained in my other answer, but perhaps I was not clear.
Please keep in mind that I am trying to help you here, and there is no need to negatively rate my service to you as your first response to not getting the information you need. I am always happy to answer followup questions and to work with customers until they are completely satisfied. Negative ratings really hurt my standing with this website, which is how I make a living. I can work with you in the other question thread if there is still anything you are unclear about regarding the legal sufficiency of one's personal testimony to carry a harassment claim. But please try to understand where I am coming from.
