The Onion

There's cases where I will play devil's advocate for such asshats. Some comic-book events feature a black Superman, and that raises questions about whether Kryptonians coincidentally match every ethnic group on Earth, or if they've got some skin colors that aren't an option for humans, or if there's some imprinting transformation wiggle-room when they show up as babies on rocketships. Remember that Supes works with a dude from Mars - cosmically our next-door neighbors - and his ass is green.

And for the constant murmur of Idris Elba maybe playing James Bond, I have to point out the sliding window of ambiguous canon. From Dr. No until Die Another Day, the previous film was definitely the same guy, probably, and beyond that ehhh don't worry about it. It was completely unreasonable that Pierce Brosnan during the handover of Hong Kong could be the same man as Sean Connery during the Cuban missile crisis - but there was no hard cutoff. You could suspend disbelief, movie by movie, and never really think about it. Did a character change? Did some details shift? Retcons happen, why worry. Don't ask what movie Bruce Wayne and his parents were seeing. For forty years, 007 was played by 6'1" commonwealth blokes with light skin and dark hair, and the unspoken through-line is that audiences can be convinced all white actors look alike. Casting anyone else would require acknowledging that the codename can be transferred - or starting a new continuity. (Admittedly less of an issue since the Daniel Craig films pretty solidly cover a new continuity with yet another 6'1" commonwealth bloke with light skin and blond hair.)

But... Doctor fucking Who? They're shapeshifters. Every single Gallifreyan gets a dozen chances (or a dozen ish, evidently) to completely scrobble their appearance while maintaining a continuous personality. Even their fucking accents can change. Any losers sincerely whining about this are being bigots about an aggressively queer and accepting production. Even the original run started with an educational bent and tried to be progressive for the betterment of its audience.

The people this article mocks might as well kvetch about Star Trek being kind of preachy.
