Simply put, whether you believe in it or not whether you support it or not, a couple of years back, the United States Supremem Court specificly ruled that burninig the Flag IS protected by the United State Constiution as "Freedom of Speech and Freedom Of Expression"
I have no personal opnion on this, but the fact remain to this day, whether you support this or adhore this, our Highest Court in the Nation says it is legal to burn it
But there are also many other law of our land that I neither support or do not support, but theruling of the Court shows & some of the rights the we as Americans have in a Free Society
Someone my say, if this is true, why then it is illegal to shout "FIRE" in a crowed movie theatre" that should be freedom of speeech/expression as well, the reason that shouting "FIRE" in a theatre is illegal has nothing to do with what was said, the Court ruled that shouting "FIRE" in a crowed movie theatre could and probably would result in a riot situation to clear the theatre, for this reason shouting it is ILLEGAL, not the words used but the where it was shouted, also the nice thing about the United States is that there are forums like this were all views can be expressed without worry or concern about being arrested for expressiing ones feelings
