It doesn’t show as flagged for me. Time heals all wounds, if your comment is not objectionable it will usually be vouched for eventually. Which is one of the reasons it’s a rule here that you don’t complain about voting. Such comments also rarely age like wine :)
You can complain, you'll just get a small karma hit for it. It's inevitable because it's off topic, but karma on HN is more or less meaningless anyway.
