Not at all. When I was a child I had lots of friends who had different beliefs but we didn't spend our time trying to convert each other. We were friends, we played, we had fun, some people went to synagogue, some people went to church, some people didn't go anywhere and it was what it was - we didn't care and we didn't judge. I see the same thing with DS and his friends (although more like: they play, they have fun, some of them like Magic the Gathering, some of them like Pokemon, some of them don't like either - they don't care and they don't judge. ;) ).
