You know what ‘hide-and-seek’ is. What would ‘hide-and-speak’ mean?

“Hide-and-seek” is a game which is mostly played by kids in their childhood. Several kids hide themselves at different locations and one kid who play a role of seeker try to find out hidden one. The expression “ hide-and-speak” in this poem expresses that the person who are black are inferior and are hidden in darkness and on the other hand people who are of white complexion put compliments on people who are black and inferior as they feel themselves as superior.
