The test to put all these tales to would be the classic “who benefits?”
Invoking an icon of the Civil Rights era such as Rosa Parks with a photo, and tearing it up in a highly public manner, benefits who?
Certainly not those opposed to government control of health care.
It benefits those who want to paint all opposition of government health care as racist.
So, if indeed this actually happened, even a cursory amount of research will reveal a deliberate attempt at provocation, by those in favor of government health care. Of that, I am certain.
