Trevor is vocal about racism and other forms of discrimination against minority groups in America and uses the show or social media to condemn wrongdoing.
Two weeks ago, he slammed police brutality in the country after the death of 20-year old Daunte Wright at the hands of police. Last month, the South African star slammed the racist mass shooting of Asians in the country which sparked protests against Asian hate.
The video drew the attention of scores of South Africans who flooded the comments to defend Trevor.
Zeno.za wrote: “Let me say this like a proper South African: voetsek.”
Kira.385 said: “Please note America didn't provide a better life for him. He created a better life for himself. Maybe you can learn from him.”
Others slammed Doug, saying Trevor's career had already taken off when he scored The Daily Show in the US.
