Personally couldn't care unless they have a strong character trait that is based on their race but in this case Gordon doesn't and well it's really irrelevant the colour of Gordons skin.
I agree, but I think the issue in the past has been that the race to diversify as quickly as possible has led to studios pushing actors of lesser ability into the role and giving them poor scripts to use, all of which make the final product worse than it should have been, leading to fans getting understandably annoyed.
However when the actor and script are good enough then their race (or gender etc) makes no difference, for example Aquaman using Jason Mamoa, Nick Fury in the MCU or Dr Watson being played by Lucy Lui etc - all of which are fully accepted without issue. It's only ever an issue when there is a combination of a poor actor and/or a poor script that 95% of fans start to complain, although there will always be that tiny 5% that complain regardless.
