In his apology released on Friday afternoon, Khumalo apologised unconditionally for the comments he made on Facebook on January 4 2016.
Khumalo is employed by the Gauteng department of sports, arts and culture and recreation as a sports promoter.
Following his Facebook remarks, an internal disciplinary was convened by his employer, where Khumalo pleaded guilty. He was given a final written warning.
“I admit that my comments were hurtful not only to white people, but also to black people,” Khumalo said in his apology letter.
Khumalo, in his explanation to the Equality Court, described the context in which the comments were made.
“I explained that I was responding to hateful remarks made online by Penny Sparrow, and those who sympathised with her.”
