Could someone help me with these 2 questions please Identify and explain the rhetorical appeal (ethos, pathos, or logos) of the photograph found on page 289 of "What to the Slave is the Fourth of July?"

Tokenism is the practice of making a symbolic gesture toward a goal, such as eliminating slavery, but not actually fulfilling that goal. Why does Douglass view his invitation to speak on the Fourth of July as an act of Tokenism?
