Query letter arrives in inbox. I happen to be working on my queries, so I see it very quickly.
I skim, category is an absolute non-starter for me; writing doesn't persuade me to consider making an exception; a LOT of other problems including word count.
Elapsed time: 60 seconds.
Me (to query writer): Thank you for your query. I'm not very strong in (category).I don't read enough of it to be an effective advocate for you.
Very best wish as you query onward.
Email inbox catches on fire; klaxons sound; IT rushes in with fire extinguishers.
Query Writer (to me): I can't believe you passed on this so quickly. Clearly you didn't read it. You're just looking for a way to reject me. (further vitriol)
Me (to query writer): I'm sorry you interpreted a pass based on category as a rejection of your work. Fortunately, most agents now are no response means no, so I'm sure you won't be insulted this way again.
