A speaker is implied, as is a possibly racially charged subject of discussion

Does the highlighted sentence mean "these words imply a speaker talking about himself/herself suffering from racism"?

Context:

Like many of his other works, Ligon’s etching White #1 (1995) is in grisaille; it presents a sentence fragment of black letters. Cropped on each side, Ligon renders the words less legible since he has marked the background with dark drips and stains, causing the letters to blend into some of these dark areas. As viewers we do not know if the phrase is taken from any well-known source. From the words that can be discerned in their entirety in the frame of the print—“of course,” “marked,” “not impose,” “hands,” “about white,” “father is not”—a speaker is implied, as is a possibly racially charged subject of discussion. It is also suggested that the sentence fragment does not intimate any issue of race, and that if the viewer makes this connection, the content of what is being “said” in the composition is neither verifiable nor certain.
