This sums up my feelings about things pretty well - I remember telling a friend that the game is interesting because its not about what it wants you to think its about.
I think a lot of people try to overcomplicate things - the story is about Booker's search for redemption for his actions at Wounded Knee. Of course I think a lot of people miss it because of the who "dog dog dog dog dog dog dog elephant" thing you mentioned - you think the game is about American Exceptionalism, or racism, or these weird quantum physical multi-universe things, and by the time you finally realize whats really going on you're so invested in those parts of the story that its hard to let go of them.
Its really all about Booker and Elizabeth and what Booker's sins have cost him and his daughter. This is why I believe the stinger is a happy ending - by accepting his sins and truly repenting them and allowing himself to be drowned he's granted the absolution.
His drowning is meant to be a baptism and the game always uses baptism as a symbol of a new beginning:
1) After Wounded Knee leads to the creation of Comstock
2) It marks the beginning of Booker's quest to save Elizabeth when he first arrives in Columbia
So when he's drowned at the end in a way deeply symbolic of baptism it only makes thematic sense that it would lead to another new beginning.
