How could I have better expressed my disagreement in that I do not find SUP's behavior in this instance particularly bad in a way that wouldn't have made you feel like I was accusing you of overreacting?

There was no intention on my part to talk down to you and I will endeavor to not come off as such in the future. I was simply trying to defend the position that I was trying to argue and would have made the same statements in talking to anybody.

If it helps to turn this around, I certainly don't feel like you were talking down to me in your comment about how IP logging can be used by mods to stop trolls. It seemed to me that you were saying that as part of the point you were trying to make and not explaining it to me as if it was something I hadn't ever thought of before.
