Your nephew is a disrespectful lil shit it seems. Or is he of your generation?
It looks to me like he took what you said the wrong way. He is feeling very hurt and your confrontation of his belief was taken as a personal affront. That's a fail on your part. I don't think it was about religion, just a failure of one person to elicit comfort from another. Religion got in the way in an anti religious way.
"Never have never will" is a faux pa.. you're saying your mind is closed.
