The automatic discount isn't illogical at all, given what we know of reality. Miracles don't happen, and they are so absurd as to be dismissed as the myths they are. You can't walk on water, you can't turn bread to flesh, and wine won't spontaneously come from water. You can't heal the sick with a touch.
Yes. I can surely discount them. THere is no evidence they happened other than the people who wrote the Gospels say so. Thats effectively worthless as evidence due to such extreme claims. There are many anecdotes saying homeopathy works, even though it doesn't. There's no reason to believe otherwise just because anecdotes say so.
