> It's common practice here to downvote comments that complain about downvotes, because they don't actually add to the discussion. Complaining about voting is frowned upon.

I answered a question.

Downvoting without giving a reason is lazy selfish cowardly trolling without contributing anything useful.

A downvote is even worse than an insult because:

- an insult shows the mindset and the stupidity of the insulting person.

- as intended, a downvote leads to deranking of the comment and thus "eradication" for many other readers who do not care to read downvoted comments or the last comments of many.
