What is Rosa Parks's largest obstacle?

Rosa Parks faced problems with white people, such as she did not give up her bus seat to a white person. Back then the blacks and the whites were very seperated, they did not "get along". she got sent to jail, and went into trial about the while bus seat issue. then proved everyone wrong.. that blacks and whites can get along very well. not many people knew that rosa parks was part of a peace school. trying to create peace between the different races.
