L.A. Dodgers star Matt Kemp -- one of the black guys Donald Sterling wouldn't allow on V. Stiviano's Instagram -- has responded to the disgraced Clippers owner ... with a pic of his own.
Kemp went to Instagram moments ago and posted an old photo of himself with Magic Johnson -- along with the following message:
"Be confident in yourself, your beliefs, and your ability to rise above it all. Most importantly, align yourself with those you admire and those who see greatness in you." #WeAreOne #XIV."
