There is absolutely no reason why most people would need to be aware of magic---be it black, white, or rainbow-colored since it is extremely unlikely bthey will ever encounter anyone with any real power.
For every one REAL magician you might encounter
You will meet several million loonies who THINK they have power but don't
And several million FRAUDS who can fool people into THINKING they are "Masters of the Occult" but who are really only con artists.
And the chances are that even if you DID meet someone with power you would never know it.
They usually don't make a thing of it.
Whether they follow the right OR the left hand path.
(And HELLO SANDRA!!!
