Since you are new to HN, you may not know this, but it is considered poor form to complain about being downvoted. And more often than not, it invites even more downvotes as a result.

From the HN Guidelines (which I recommend reading):

> Please don't comment about the voting on comments. It never does any good, and it makes boring reading.

If it bothers you this much, you're better off deleting your comment.
