It seems pretty clear to me that you're denigrating this woman. And when you say "she really didn't do much of anything" that pretty much tells me you didn't really read any decent biography. Just readying the blurbs on various websites about her life tells me she did a lot in her life to help civil rights.

She also recieved the highest possible civilian award (Congressional Gold Medal, I believe it's called) in 1999, a tribute to what she did with her life.

Like I said, it seems like you've got an some weird anti-Rosa Parks agenda that actually does, honestly, make you come off a bit racist. That being said, tell me what biography you read that lead you to believe that she didn't do much.
