Yeah, but you're right, that IS the charm. It's a shame that people can be sensitive. I mean, nobody is actually suggesting that anyone shoot little Buford, be a dog or a child (well, I guess he'd be a bear cub). It's just a hyperbolic statement about how misbehaved Buford is.
All that being said, the dated songs and humor are what don't connect with audiences today - or do they based on those lines today?
A mondernization is not a bad thing though, and better than just getting rid of them completely.
