What Major Intellectual Issue Most Keeps You From Accepting The Christian Narrative?

[downbeatplumb]

Hi Friends 

I hope this is the right sub-forum. I'm currently in a Christian apologetics class, and I have been assigned a project. I need to find a non or "ex" Christian and ask them what the most significant intellectual issue they find in the Christian narrative. Would anyone be willing to help me out with this? 

You would simply state the most important issue that discredits Christianity as a rational position, whatever it might be, and then I will prepare a Christian response to whatever objection you raise and send it to you. You would then read it and send me back a short paragraph or so (or more) detailing your response to whatever I've written. If you are willing to do this, then either post your issue below or pm me. It would be much appreciated. 

Thanks!

The entire idea of theism seems like childish nonsense to me. So I would have to say all of it.
