Also, one thing I think people ignore is that BrandonM's comment was notable because it was voted to the top.
Which means that the people reading and voting on the thread, at the time, thought it was the best reply. But no one will ever point a finger at them, because they're anonymous. They also have less chance for self-reflection - who remembers an upvote?
I also think people might overlook BrandonM's follow-up reply to dhouston's reply on April 6th - "All of your feedback was well-thought-out and appreciated; I only hope that I was able to give you a sneak preview of some of the potential criticisms you may receive. Best of luck to you!"
I think the biggest issue with people is a lack of introspection, and this example shows the issue here. Most interactions are too meaningless and therefore difficult to self improve on.
I don't know what's the best system to make people reconsider their actions, however. After all, giving a single upvote and walking away is incredibly easy. Coming back to recognize your mistakes is hard.
