Excellent point you raise Angela!!!!!!
As a teacher of children with mixed races in my classes, I did not incur any difficulties in teaching black students than I did white ones. Children that truly want to learn, and those whose parents see the value of doing so, were not concerned with my race, as a teacher. All they wanted was their children learn to swim and see progress in the process. I guess I was fortunate that I didn't experience this, but that's not to say this wasn't the case for some other black swim instructors. However, I did find that the higher maturity level of the individual, the lessor chance a black swim instructor will experience friction from those of non black ethnicity that truly were interest in learning how to swim. Another factor, I believe was an asset to me not experiencing such sad occurrences, is the fact that I had such a personality, that refused to be defeated in achieving the objective of "each one, reach one, teach one", no matter the obstacle that needed hurdling.
