9/11 was more concrete than symbolic, a lot of lives and property were destroyed. Burning the flag is more symbolic than concrete; physically, only some cloth is lost. If I have a flag made with 51 stars cleverly arranged such that it appears to be a real American flag to the casual observer, and I burn that, then I've probably "outraged" some of those casual observers, but I have not burned an American flag. This indicates the importance of understanding symbolism.
This idea that mob action is somehow protected free speech is getting out of hand. People seem to be losing the ability to distinguish between legitimate protest and vandalism or worse. Personally, I don't want to live in a country where the group with the largest and most violent mob controls public policy.
Can't believe everyone is getting their panties in a wad over this. I can only remember a few times in my life where a flag was burnt in America and I don't recall anyone being hurt much less killed in the process. A lot of emotional anguish for an action most of us probably will never see in person. But heck let's pass a law banning this so when it happens again in five or ten years we'll be ready, gotta protect the children.
When I have I EVER "bragged" about it? Say that reminds me. You appear to be awfully grumpy lately. Business in the toilet? Impotence? Bad trade? Incontinence? Catch your mail man making a special delivery to the wife? ???
