So you picked the parts you liked and ignored the rest? Alright. Now give this next question some serious thought, because I'm not trying to offend. Why did you do that?
Because it's part of my personal take on the religion. I personally think that God, the great, universe-creating being that he is, has much more to worry about (like keeping physics in check or preventing the universe from unravelling like a string) than gay people and people getting divorced.
