No she didn't. Her famous bus protest didn't affect change by itself, but helped spark the LA and Detroit riots which DID. She did NOT believe in pacifism according to her autobiography:
"Although Parks' autobiography recounts early memories of the kindness of white strangers, she could not ignore the racism of her society. When the Ku Klux Klan marched down the street in front of their house, Parks recalls her grandfather guarding the front door with a shotgun.[10] The Montgomery Industrial School, founded and staffed by white northerners for black children, was burned twice by arsonists. Its faculty was ostracized by the white community.
Repeatedly bullied by white children in her neighborhood, Parks often fought back physically. She later said that “As far back as I remember, I could never think in terms of accepting physical abuse without some form of retaliation if possible.”
