That's BS
Professors: US flag symbolizes racism, should not be displayed on campus

You ignoramuses will have no defense against this either. Nor will you have any defense when they come after the founding fathers nor will you have any defense against most of American history pre 1965. It's all racist.
So, some fringe professors sign an online petition, which (unsuccessfully) called for the American flag (among other flags) to be banned in a single specific location on the campus of a single liberal university (not even the whole campus, just the lobby of one building), and you think THAT poses a threat to the American flag? Ha!
I would bet you my friend, that this “Professor” would not know that Stars and Bars is a confederate flag.
