The 36-year-old son of Prince Charles and the late Princess Diana spoke at this week's British GQ Heroes conference.

Harry and Markle, who is the daughter of a Black woman and a white man, left their full-time work at the House of Windsor earlier this year and moved from Britain to California.

“You can’t really point fingers, especially when it comes to unconscious bias,” Harry said in his GQ chat. “But once you realize or you feel a little bit uncomfortable, then the onus is on you to go out and educate yourself because ignorance is no longer an excuse.”

Earlier this month, Harry and Markle, the Duchess of Sussex, called for an end to "structural racism" in an op-ed in London's Evening Standard.

"If you are white and British, the world you see often looks just like you — on TV, in media, in the role models celebrated across our nation," the pair wrote. "That is not a criticism; it’s reality."
