Stewart called Kaepernick a "dumbass" and an "idiot" on Twitter, resulting in a certain kind of backlash he may or may not have anticipated.

Many people responded by saying, "Didn't you kill a guy?"

What people are referring to here was the fatal incident where Stewart hit into and killed Kevin Ward Jr. during a race at Canandaigua Motorsports Park on Aug. 9, 2014.

Someone else accused Stewart of being racist.

He responded by saying that he had a black roommate for five years.

Stewart tried to set the record straight on Monday.

The takes on Kaepernick since Friday's protest have been ubiquitous.

Just today, former NFL safety and NBC analyst Rodney Harrison criticized Kaepernick, saying, "I tell you this, I'm a black man. And Colin Kaepernick — he's not black."

Harrison has since apologized and said he didn't know Kaepernick was mixed race. Twitter took that and ran with it.
