Why do non christians ask sarcastic questions about our beliefs?
Many millions of people have been feed the line that your beliefs are somehow reasonable. Not only this, people who believe in your religion have used their belief to make discrimination legal over and over again with the most recent case being in CA. To top it off, many Christian, actively encourage their children and others to be willfully ignorant and to equate belief with science and evidence. The point to this is that you have been feed a line that your book is true, while there is absolutely no compelling evidence that it is anything but fiction based on a few historical events, and no, the first five books have no historical events in them at all.
