When someone goes through many SO questions a day looking for something to answer as I do, they may cast downvotes and close votes on questions readily and move on. Some people — especially the question asker — may view these votes as negative or even toxic.

Of course that’s negative. Even worse, downvotes in and of themselves are useless. They provide no actionable feedback, no way for the asker to “improve” their question.

Especially if the asker *is* new, a downvote is a slap in the face. It’s lazy, and again, useless other than as a way for you to assert your superiority.

You brag about that, and then say you’ve become more helpful and less snarky.

I don’t see any evidence you’ve done anything of the sort.
