That goes for all religions dude...
Yeah I know. But this is like my only time I have talked to religious people so it's kinda special for me.

One good one was our discussion about free will.
Me: I don't know, I don't think we have free will, it's mostly illusion, we make our choises based on our experiences and things we are born with. There is no "greater thing" guiding us, only the already set parameters we do our things based on.
The idiot: But you can close your eyes when you are driving in a heavy traffic, don't you?
Me: Yeah, but how does that...
The idiot: So you can make choises.
Me: Yeah, but again, how does that refute anything?
The idiot: We can make choises based on our free will. If you read the Bible, this comes clear.
