Take what you need and leave the rest, someone said it above too. The people who speak are just that, people. Not everyone will have the same beliefs or values or opinions. And I think the same as you, that It is my decision. At the end of the day, it will be me who decides to pop that cork or not. But I also think that picking apart the god theory and free will, etc. is a way for me to not commit to anything, I can argue it all away.
Try it out a few times. I look forward to going now.
