I downvoted you because you self-voted yourself to the top with a low-quality comment. If you want to self-vote to the top, at least post a long comment or something that contributes to the conversation or the post.

I like comment sections clean, so I clean them with my votes. I upvote the good stuff and downvote the bad stuff. If you're angry about that, then either make good comments or don't upvote yourself to the top.
