A few days back, I discussed (here) why one should test one's logical hypotheses against something alien, be it a Medieval paradox, a Sanskrit text or the perspective of a thinker being outside the mainstream (e.g., a disabled at a time in which disabled were not allowed to be part of the mainstream society).
Today, I came back to the same thought while reading Adriano Mannino's post about the diffusion of theism among philosophers of religion. Adriano discusses the worries of some philosophers who think that "philosophy of religion" is in fact a disguised Christian apologetic and is, therefore, not philosophical at all. Personally, I think that apologetics can be (and often are) philosophically interesting, but readers of the Cocoon might remember that Moti Mizrahi had manifested in a comment here his disappoint with the fact that journals on philosophy of religion tend to focus only on Christianity and disregard even Judaism.
Whatever the case, should philosophers of religion want to reply (I am not saying they should) to this attack by showing that they are genuinely interested in their subject and not just in justifying their personal choices as believers, they could try to engage in religions and theologies different than their own or at least different than the Christian one. (By the way, if you are looking for an excuse to start doing it, have a look at this call for papers).
