I think conversation with anyone about that kind of thing is good as long as they're willing to engaged. If they have thought about it you get a different viewpoint, if they haven't you give them something to think about

I don't really take a stance either way on the free will thing because I think it's a made up concept whose existence entirely depends on your own definition of the word

Unless you believe in some kind of immutable soul that's separate from the physical body and brain that is in charge of decisions somehow I suppose
