Yeah...having re-watched avatar with my son not that long ago I don't see where the issue is. Downplaying/removing his chauvinism and sexism only serves to negate his character arc and more importantly undercuts the hilarity of watching his shit get kicked in by Suki and the Kyoshi warriors. I think if anything: the only part that has aged poorly is the part where Suki falls for him. Still kinda would have preferred it if he had thought that's where it was going and she'd have been like "....whoa....dude...we're not...no...just no...". Too many of these stories end with these characters getting romantically entangled with each other and not enough end with them just coming to respect each other as peers.
