I don't know why I didn't peg this one as a false argument much earlier.
You can often tell when there's an amateur skeptic lurking around some random debate, because at some point they're bound to upchuck their own particular version of the unoriginal and silly Unicorns, Leprechauns and Flying Spaghetti Monster (ULFSM) arguments made prevalent by the New Atheists among others. Dawkins did it with the Gospel and the Knights of the Round Table in TGD, and if you're at all into these types of debates, you've likely seen it go down for yourself:
"I've got legitimate reasons for what I believe," proclaims some reasonable believer.
"No you don't," quips a flippant atheist. "Do you have legitimate reasons to believe in Unicorns, Leprechauns and the Flying Spaghetti Monster?" (Hehehe I the atheist outsmarted you the God-dummy! is the usual subtext).
Just for fun, let's take a look at this idea that ULFSM are accurately comparable to God in an intellectually honest discussion of things.
