PS: "How about demanding all people have to stand for the national anthem or they don't love their country."

Actually it used to be stand, then it became stand and remove your hat; then it was stand, remove your hat and place your hand over your heart. Tomorrow it will be stand, remove your hat, place you hand over your heart, and extend your other hand out in a salute to the homeland or you will be labeled as someone who would spit on the grave of the tomb of the unknown.
