I am doing the courtesy of telling you why I downvoted you.
If telling you why I downvoted you then also compels me to justify my position in an extended way, then I will not do it in the future. Instead I will just silently downvote when I feel it is warranted.
I could put the effort in, that's true. But I'm not going to be obligated to, and I'm not going to be shamed into doing the work to educate you.
I'm glad someone else did!
