If you have an issue with a particular moderation, I suggest pm'ing the moderator.
I wouldn't do it in an angry way, and it would have to be a good-faith question or issue, but in my brief experience, I don't think that they are unreasonable.
Finally, I would note that the signal-to-noise ratio here is excellent, and I think that the main reason for that is the excellent work of the moderators. I would rather they moderate a little too quickly in order to keep the peace, than let it go and have it devolve. YMMV, but that's a feature, not a bug.
