I actually had to reject a comment today. It was posted under a topic that the comment had no bearing on. It was a short comment that had no real subject. I think it was a kid that thought he/she or it was funny.
I am an advocate of free speach, but it must be on topic and somewhat intelligent. I say "somewhat" because I know that is all I am. In most cases I am just stating my opinion and how I view the story or situation. It may not be based on research, it may only be gut feelings on how something was written. Other times I may post on what I see.
I wonder if people really care about what is going on in this world or if they just think posting absurd comments is more important.
On the other hand, it just doesn't matter.
