Imagine university classes that take seriously the Mormon conception of a god who has a body with a plethora of wives living on the planet Koleb. Can you imagine atheist philosophers of religion bothering to teach such classes? I can't. Wouldn't doing so be to give those beliefs legitimacy in their own right? Now imagine an internet atheist who publishes the latest argument on behalf of this god, saying "Here's a new argument for the Mormon god I just discovered." Isn't this also silly? My guess is we wouldn't take atheists seriously who did these things, just as we wouldn't take seriously the arguments themselves. Why should we take any atheist seriously who thinks there is a good argument for the Mormon god? Why should we not transfer this same line of thinking to the Abrahamic gods?; or the Norse gods?; or the Greek gods?; or the Egyptian gods...? I think we should, thus destroying the philosophy of religion in the process. Yes, I'm serious. To read a more complete account of this see here.
