What is the difference between an 'Abstraction' and a 'Facade'?

Lots of developers think that testing private methods is a bad idea. However, all examples I've found were based on the idea that private methods are private because calling them could break internal object's state. But that's not only reason to hide ...

I would the private methods in your facade are likely to be public methods in one or more other classes.
I think you are putting too many responsibilities (implementations) into the facade.

The DataContext has a generic method to retrieve the table you want:
var table = dataContext.GetTable<NewLetter>();
Maybe you could use that to rewrite... .
Your tables will need some kind of discriminator column/property.
Look at inheritance in Linq2SQL.

Something like this

In short, if you do this:
class Wrapper(object): def __init__(self, wrapped): object.__setattr__(self, 'inner', wrapped) def __getattr__(self, attr): return getattr(self... .
This is where you use the __setattr__ and __getattr__ methods as documented here .

You should title this, "Behind the happy Xbox facade"?
