What are we supposed to make of people carrying the Confederate flag, as well? The Confederate States of America fought a civil war to preserve the enslavement of Black people (as specifically mentioned in most of the state constitutions of the CSA states)- what message are they trying to send by bringing that flag to the capitol building?
