Are Arguments for Theism Cases of Special Pleading?

Here's the charge:  Any deity proposed as a explanation is in fact not one, as declaring it to contain its own explanation is simply special pleading.

To diffuse the special-pleading charge, it's helpful to keep in mind the distinction between the use of the word "God" as a proper name and it's use as a position. For instance, the word "boss" is a position that could be occupied by a number of individuals, while the word "Daryl" is a proper name denoting just me.

When using the PSR to argue for a self-existent being we’re concerned with the sense of "God" as a position. The PSR, if correct, holds that it is necessary that some entity or other hold that position. 

In other words, in using theistic arguments we're not arguing that we have some deity in mind (who just so happens to be named "God") and that he must be exempt from contingency - rather, we're saying that, given the PSR, some being or other must fulfill the role of a concrete necessary immaterial being, that something occupies the position of God.
