1) How can an object be racist? Racism is an emotion or paradigm, a flag possesses neither. Furthermore, it is not a symbol of racism by those who wave it. I have never heard anyone who displays a confederate flag say "I wave it because I am racist, and this flag is the symbol for racism". They say they are interested in state's rights, an agrarian society, rebellion against industrialism, etc.
2) Because society views a certain action as wrong, does it make it so? Under that line of though, slavery was "right" in the 1700s because a majority of people thought it was so. Or the Holocaust was "right" because a majority of Germans in power felt it was so. What is the critical mass required to make something right or wrong?
So because a majority of people incorrectly associate the confederate flag with racism, and nothing but racism, that makes those who brandish the confederate flag racist. So, I should be careful what I do because of the ignorance of others possibly misunderstanding my intent. That is the same line of reasoning that I see punk gang people beat up innocent people because they have a red polo shirt on in the mall.
3) What does 'step you game up' actually mean? If it means become an educated person, perhaps you should step your game up as your comment only seems to propogate and justify the ignorance of society.
