How about just letting things go and acting like grown ups? I am certain there were several posters who had no sources and were just trolling. I am also certain there were several who heard from people they trusted that Gruden was coming.
Trash talking to the former only encourages them (it is the entire reason they post). I was once told "never wrestle with a pig, because you both get dirty, but the pig likes it."
Trash talking about the latter makes you seem like a belligerent child, you end up looking far worse than either the trolls or those who were misled by their sources.
