Face it, daredevil is a white superhero, it just would not work if he was black. Spider-man is also a white superhero 9however his ultimate universe counterpart is black). The point is the whole thing would be painfully PC. Why can't people just get over this race thing and accept the majority of superheroes are going to be white because the US' majority is white. It does not mean all superheroes need to be white in films, but if they're white in the comics, why bother to make them black in the films? On the other hand, Kingpin's white in the comics, but was black in the film, and he was playedreally well.
Okay, can you tell me what part of Daredevi's character is so intrinsically white? What is there about his persona, his identity and his abilities mean that he could only be played by or drawn as a white man? Is he a member of the KKK or something?
And why is it okay to make Kingpin black (and I happen to think that Michael Clarke Duncan was a great choice) but not DD?
In the comics, Daredevil is smaller and slighter than Ben Affleck, with a different hair colour. Bullseye, unlike Colin Farrell, is not Irish. Elektra, unlike Jennifer Garner, is Greek. You can accept all of that and the change of Kingpin's colour, but not that of DD? Why not?
Off the top of my head, most actors to play superheroes have been quite different from how the characters have been drawn.
Toby Maguire has a rounder face and goofier smile than most comic Peter Parkers. Michael Keaton is smaller, skinnier, less classically handsome and has a receding hairline unlike most depictions of Bruce Wayne. Val Kilmer is blond. Tony Stark has usually been drawn to look like Errol Flynn or a young Timothy Dalton (and Johnny Depp in the Ultimates). Robert Downey Jr was older, shorter and more craggy-faced but nearly everyone loves his depiction.
Mark Ruffalo, Ed Norton, Eric Bana and Bill Bixby look nothing like each other but we're all expected to accept that they're an accurate take on the same man. Ian McKellen has less muscle and physique than how Magneto used to be drawn. Patrick Stewart (who arguably looks more like his comic character than 99% of comic cast-actors) plays the New York-born Prof X with an English accent. Jackman is a foot taller than the Wolverine of the comics. Alfred Molina, unlike the comics' Doctor Octopus, looks nothing like Elton John. Harvey Dent is usually drawn with brown hair, not Aaron Eckhart's blond hair. And the Joker in the comics has genuinely white skin and green hair, unlike Heath Ledger's take (nor was he as paunchy as Jack Nicholson).
Most people's objection to Keanu Reeves' depiction of John Constantine was not his hair colour or accent but the fact that he totally failed to capture John's cynical wise-cracking persona.
Given all of that, I can't see how changing the colour of characters - so long as the actor captures what makes up the character's persona (imagine a young Denzil as Batman or a young Will Smith as Spider-man).
I'd argue that the two comic movie adaptations which look most like the actual comic come to life are Dick Tracy and Popeye. And how often do you see them topping people's list of their favourite comic book movies?
