All right, I’ll confess to not having read the story (no link provided and I was being lazy) so I shouldn’t really defend the crowd. I will say I would take a person’s protest against the flag to be meant against the United States, not against the policies of whoever was president at the time. The U.S. flag represents our country, not a person or party, or even current actions in which it’s engaging. I’m understanding (though I still haven’t read the article) that this girl’s purpose was to denounce the current actions of the U.S., not to say that the U.S. as an institution is bad. However, it is at least reasonable to see how someone sitting in the crowd would take her actions to be protesting the country that has provided her a great deal of freedom and thus think of her as ungrateful.
