I'm not a specialist in either, though I know of Plantinga and don't dismiss him as a preacher. From what I was able to find, there's engagement on this topic with back and forth, so I'm not sure it's settled. I'm not sure how much LW posts are discussed by an out-group.
On knowability, the SEP says: "There is no consensus about whether and where the proof goes wrong", so I'm not sure this is a good example of a trivial issue either.
And I wasn't claiming philosophy contains no flawed arguments, but dismissing the entire corpus rather than peacemeal attack seems reactionary rather than reformative.
