Would this be considered a shortcoming for Rosa Parks? I'm still having trouble finding somethings for this part of my presentation.

She lost her job at the department store when the department store she worked at heard about her arrest, and her husband lost his after his boss forbade him from speaking about his wife or her legal troubles.

Those weren't Mrs. Parks' shortcomings. They were shortcomings (crimes?) of the society in which they lived.

I don't see any shortcomings for Rosa Parks.
