Disclaimer: Piratecat, I would love for us to be able to continue the race debate in a mature fashion. If you don't think that is possible, I'll understand.
ShinHakkaider, I think PC called it right on. In this case at least, I don't think any of the objections are motivated by racist feelings. Most often, we fanboys (and fangirls) get worked up over changes that seem arbitrary. Witness the endless debates over the most minor details in the LoTR movies.
I am a big Daredevil fan, but I am also a Michael Clarke Duncan fan. When I heard he was cast as Kingpin, I was thrilled. I said before that I am opposed to arbitrary character changes, but I do not have any problems with a race change, made to allow a good actor/actress to play the part. As others have said, this is fine as long as race is not a defining characteristic of the character.
In fact, I was far more concerned that Jennifer Garner does not look Greek (and I am a fan of Ms. Garner and Alias, I just did not think she was right for the part).
For the record, I have no problem with Catwoman being black, although I am no fan of Halle Berry.

SO everytime I hear "why John Stewart" or "she's not black in the comic" it sets me right off...
Again, I think you are mistaking the intentions of those who complain about Jon Stewart in the Justice League cartoon. He is one of my favorite Green Lanterns, but for THE cartoon, many felt that they should use the definitive, iconic versions of the characters. That means Hal Jordan. Some did not like Wally West for the same reason, but in my opinion he has become the definitive Flash, and has been that character for some time now (braces for flames).
