Downvotes don’t mean anyone’s upset, there’s a large variety of reasons people downvote. Same is true of upvotes, there are lots of different reasons for them. Try not to take either personally.
Downvotes don’t require explanation, just like upvotes don’t require explanation. It’s a great idea to be curious and seek ways to avoid downvotes, always good to assume you might be wrong. Less so to demand you were right, even if you are. :)
Also be aware that HN guidelines suggest avoiding complaining about votes you get, https://news.ycombinator.com/newsguidelines.html
Hope that helps, cheers!
So thank you for explaining the situation to craftinator :-)
