At what point do you abandon the idea of leaving a comment? I give up when I see the thread bypass a half dozen. At that point, the probability is high that your comment will get steam-rolled by someone’s “superior” opinion. It’s simply not worth the time or effort to debate so that you can prove that you are right. But really, we are more concerned with proving someone wrong in those debates, am I correct? I’m probably wrong, and I’m sure you will debate me on that.
However, It’s quite horrifying (maybe entertaining) to read through a comment chain once it gets over one hundred. You really see the broad spectrum of people’s beliefs and opinions.
