Chester is as racist as Uncle Ben. Uncle Ben has a picture of a Black (presumably African-American) man. Is that racist? The company, Mars, thinks so. If that is true, then Chester is racist.
Other examples besides Uncle Ben and Aunt Jermima might be Eskimo Pie ice cream, Frito Bandito mascot for Fritos, Miss Chiquita of Chiquita Bananas.
I am undecided at this point.
