Hey, look! They're just as stupid as the people who were burning Qurans! No better, no worse than the other situation.
... just childish.
You're right. Childish and wasteful. Muslims view the Qu'ran itself as a sacred item, not just its teachings inside. Christians view the Bible as just a book, so burning a Bible doesn't have the same kind of... inflamatory effect. No pun intended. Burning any book, religious or not, is foolish.
