I know we're talking about characters, but Bashir's actor was born in Sudan, is half Sudanese, and his birth name is "Siddig El Tahir El Fadil El Siddig Abdurrahman Mohammed Ahmed Abdel Karim El Mahdi" as an FYI.

Haha. You aren't wrong.

... Bashir is clearly intended to be of middle eastern or perhaps Indian descent, somewhat obvious from the actor. And the episode with his parents, also both clearly not white.

He was genetically engineered because his parents were working class and were worried that their kid would be too dumb for even that. He's not exactly high society.
