With all due respect, this topic is alive and well for the same reason people post the "Benchmade Griptilian vs Spyderco Endura" threads, or the "S30V vs 154CM" threads in General. Why are you so bothered by a discussion that you are not at all obligated to participate in? If folks want to talk about it, why stifle and extinguish it?
If we followed your ideal of what is worth discussing, the whole forum would pretty much come to a grinding halt. What is left worth discussing? The opinions that may have changed from some people perhaps that felt one way, but changed their mind? Te desire for some new members to understand? Some insight into experiences from folks here? Lots of reasons to be discussed. If it bothers you to such an extent, please feel free to browse other areaas and contribute what you can there.
