Well, you are both right...
In fact, the Pi has the potential
of having a serial port, but it is not (in the default setup) accessible to the user. And you need additional (active) hardware in order to make it accessible.
As a matter of word definition, I would say that if you one needs to add additional hardware (beyond, say, just a wire and/or a jack - and some soldering) in order for a feature to be actualized, then it really is fair to say that the feature does not exist (before the additional hardware is installed).
And some folks need to stop being fanboys and see the forest behind the trees.
