I'd like to see the original story sourced, please. If someone has a link to an independent news article that describes Mrs. Bush as "being upset" I may believe that she cancelled a meeting with women who were going to wear the white scarves. Otherwise, I think the white scarf story is- forgive me my next phrase- a red herring.

...And just how did Mrs. Bush know they'd be wearing white scarves as a "silent" protest? And who were these women? And why were they to be meeting with Mrs. Bush? Too many questions, folks...
