:I respect your advice and your experience. I must say, though, that many times in the past when other editors have counseled more good faith, I have correctly predicted that good faith wasn't warranted. At the same time, there have been a few instances when I was wrong. I tend to look at as a cost-benefit analysis in terms of how much time do I spend being more patient vs. how often it reaps rewards. I have to decide how to prioritize my time on Wikipedia, and I already spend a LOT of time here. 

 :I hope you noticed that I did take your initial advice to heart and posted something more conciliatory on the IP's Talk page. 

 :Thanks again for sharing your thoughts with me. I really do listen and consider what you (and others) say.
