Freedom of speech and the old Flag

Can SA Rugby ban the old South African flag at rugby games? In this morning's Die Burger I argue that they can.

Should SA Rugby ban the old flag? I would say yes, they should because their image is at stake and waiving the flag at a rugby game somehow implicates all of us who watch the game in a yearning for apartheid.

Should the old flag be banned by Parliament? I would say absolutely NO, because that would suppress unpopular political speech, which can only be bad for democracy.
