I dont see how deleting threads that get out of hand solve anything.
It is only a small hand full of people who are ruining genuine debate.
They post relentless antagonistic comments and pounce on any new comment repeating an opinion they have stated an already ridiculous amount of time.
Their intention is to drag the new poster into their moronic and monotonous discussion.
Its always the same people people who turn what could be an interesting discussion into this outdated Wests v Balmain crap. You all know who they are!
Instead of deleting a thread perhaps not tolerating their behavior and limiting their input to the one or two valid points they have before the thread turns into their own little form of entertainment might be a better idea.
