It is not always possible to avoid offense, even among the truly virtuous.
A very religious Baptist friend who would means no harm to anyone, quite the opposite, believes absolutely that my Buddhist Thai mother-in-law is ultimately bound for hell, because she is a Buddhist.
But, he is also absolutely rooted in conservative values of choice and tolerance. He just doesn't think there is a heaven for my mother-in-law. :-)
But that is just one persons opinion, my own.
A rather good opinion, I think.
