The problem with people nowadays is that they're too sensitive to honest and insightful criticism. Sadly, the unwillingness to be open to unedited criticism is a leading contributing factor to ignorance. With that said, it should be noted that that's not what this thread is about at all.
merlyn's post was a simple correction of incorrect code. Computers don't know anything about 'soft skills' so often there's a disconnect between what people intend and what they convey in their code. I personally appreciate it when someone points out an error that I either may have made inadvertently or that I simply didn't know was an error in the first place. I don't critique the way the error was made known to me, I just accept the fact that I made a mistake and learn from it. Perhaps you'd do better to do the same.
