A Purple Ribbon is the New Symbol of Commemorating The Attack on America-Unproven!
Summary of eRumor:
The email says that just as the yellow ribbon became so visible during Operation Desert Storm and the Gulf War, the purple ribbon is becoming the same for the Attack on America.
There’s no way of knowing the answer to this one since it is not an official effort but apparently one that has been started by someone via email.
There has been a lot of visibility given to the red, white, and blue ribbons that are seen on television and on the Internet. Unless the purple ribbon idea catches on, it seems that those have already become the symbol.
