"I've never experienced what you describe, so it must be either imagined or your own fault."
I've seen this nonsense over and over again in communities of all kinds, most often in tech forums (where there are always a few participants suffering from a big-fish-little-pond effect). It's a very rude and foolish bit of human behavior.
There are more things in heaven and earth, Horatio, than are dreamt of in your philosophy.
