Your conclusion is wrong - she admits in the quote you referenced that segregation was there. She does not say it didn't affect her, she says she didn't feel it (as in let it affect her own behavior, cloud her mind, react to it, etc).

To my recollection (I could be wrong it's been years), the movie didn't focus on her feelings about segregation, it focused on the actual segregation and the effects of that segregation on her daily life (i.e. obstacles that would have been in her way), which is distinctly different from her feelings about said segregation and obstacles...which is what she's referring to in the quote.

The book actually touches on this:

"She knew just as well as any other black person the tax levied upon them because of their color. But she didn’t feel it in the same way. She wished it away, willed it out of existence inasmuch as her daily life was concerned.”

MANY members of different marginalized groups deliberately choose this outlook as a method of self preservation in an attempt to minimize the very real emotional, physical, and spiritual toll created by these -isms. Quite a bit of research on the topic if it's something that interests you. But their choice not to acknowledge the source of these obstacles (i.e. racism) doesn't mean it's not there and it doesn't mean there aren't significant challenges...
