Was Walt Disney racist?

If you approach this in a logical manner, is it really racist to depict different cultures with mannerisms and expressions that are true to the culture? Historically, do people of Siamese culture eat with chopsticks? Yes, so is showing Siamese cats in the Aristrocats as Siamese with chopsticks, singing about being Siamese, a racist statement about the Siamese people? The movie, Song of the South, is an adaptation of African stories handed down by slaves. Yes, he does speak in an old southern dialect and sounds to some as "slavish", but that was the time the stories were told, so it stays true to the culture. I believe the Disney movies are pretty true to the time periods they represent, hence, the characters depicted are true to the culture in time. Is is racist to show the truth about people? We all SHARE many mannerisms and characteristics. We can see ourselves in other people and cultures. I'm sure I can think of other races that eat with chopsticks, even the white man in America. I can think of many white people who talk in an very southern voice that call themselves redneck. Most of Disney's movies have a lesson to be learned that is for ALL cultures.
