Racial Disney-fication

There's an aspect of this movie and others like it, such as the made-for-TV remake (also by Disney) of the musical Annie that I personally find somewhat troubling. I wonder if anyone else feels so as well. What I'm talking about is the anachronistic way in which race relations are offhandedly portrayed in these films. The black people in these films seem fully integrated in the town in which the movie takes place, River City (which Meredith Willson supposedly based on Mason City). Black and white children are shown playing together in the streets. All of the black people in the movie wear the same kinds of clothes as the white people and exist alongside them without issue. In the scene in the cafe, two of the patrons are a white man and a black woman sitting at the same table. The movie takes place in 1912. While it would have been nice if this kind of environment was actual, it probably wasn't. Most blacks at the time were not at the same class level as whites, and had to worry about things like the KKK. Racially motivated lynching was not uncommon, nor was segregation. I feel that the way blacks are portrayed in this film whitewashes the truth about this country's history, and perhaps even trivializes their struggles at the time by erroneously portraying an environment in which those struggles didn't exist. I'm more annoyed by this than angry about it, but I do find it offensive.
