If you think that I am a language Nazi, then pay a visit to the Underground Grammarian. His stern visage reminds me of a passage near the beginning of Franz Kafka's Vor dem Gesetz, "Before the Law." The protagonist seeks entry into the Law, but at the door stands a guard who warns:
Ich bin maechtig. Und ich bin nur der unterste Tuerhueter. Von Saal
zu Saal stehn aber Tuerhueter, einer maechtiger als der andere.
Schon den Anblick des dritten kann nicht einmal ich ertrage.
I am powerful. And I am but the least of the gatekeepers. From room
to room there are gatekeepers each stronger than the next. Not even
I can bear so much as the glance of the third. (tr. BV)
