I didn't think that by a vacuous God you meant a non-existent God.

Obviously, theists don't need to pretend to be atheists: Theism is respected by everyone except a small minority of neo-militant ultra-materialist fundamentalist atheists. To be taken seriously, theists merely need to be (or pretend to be, in the presence of critics) moderates, i.e. believers in a God that acts in a very subtle way and conforms to modern secular morality.

So no, "we" haven't won. The limited form of insanity we call faith is still the norm and is still respected.
