The 2,977 flags have been put there in effort of the both the Republican and Democrat students in remembrance of the 2,977 lives lost that tragic day of 9/11. It is one of the very few times left, and right wing beliefs come together and honor those whom they love so dearly.
It must be known that even though you do not agree with others beliefs, it does not give you the right to break the law, or vandalize property out of emotional rage just because you do not agree. To start accepting destruction of property out of anger from personal beliefs as "Free speech" promote breaking other laws just because we don't like what those people love dearly.
