I've never been too bothered by changes like that. I remember in Superman Returns when Perry White says "Truth, Justice, and all that stuff" or something, people were offended.
Like the thought of removing "Under God" from the Pledge of Allegiance makes people mad, even though it was something tacked on after the fact and not part of the original intent. Some food company a year or two ago used the slogan "One Nation, Indivisible" and it bothered people. Slow news day, I suppose.
Superman is the superhero for all people, nations, not just middle class white america!
