On my side? What side is that?
Are you on both sides of all issues? This is a religious debate forum. One side has faith, the other side would lack it. Every Atheist or agnostic I debate eventually compares something with Harry Potter books. Textual comparisons are not extraordinary. Comparisons with the same book consistently are.
Ok. Lord of the Rings then. There's a creation story in Silmarillion, I think.
That is probably because it was written by a man with faith. The guys who wrote chronicles or Narnia (Lewis), ethics of Elf-land (Chesterton), and LOTR (Tolkien) were all men of faith and come up together.
Since all of these added together are not a meaningful fraction of the total sales or importance that the Bible is that even if all were Atheistic writers I do not see any comparison possible. I no longer even know what your point is.
The three major religions in the this world were all promoted with violence and war at some point. At least we haven't seen any Harry Potter wars yet.
1. At least for Christianity the violent promotions have alienated more than they have convinced. If history tells us anything massive casualties almost always strengthen resistance. Look at London in 42-43. Even Japan's military advisers were more wiling to fight to the death after the atomic bombs. Thanks God they had a reasonable emperor. The crusades were about land and wealth, the inquisitions were about church power, Conquests about Gold. These are human motivations not Biblical. I would say Christianity thrives in spite of violence not because of it. Islam is another animal all together.
2. Harry Potter is full of violence. It's violence sells, it's violence promotes.
Most bought, or most own doesn't always relay most read or most liked.
That is true but since the numbers were about 20 - 1 I do not think that is going to help you. I guarantee you also that more people have worn bibles out be reading them that Harry Potter books at 50 - 1. However I have no idea to get reliable stats on them.
I haven't read it either, but I think I know why it's so popular.
I have seen the Potter movies, they are good. I have never heard of nor even know what shades of grey are about but I guarantee they will both be virtually forgotten at some point in the future and the bible will still be as popular as ever. The bible has buried it's undertakers for thousands of years.
How did this popularity contest get started? This is not usually my thing.
