What I would like enforced is the rule against ad hominem attacks. I would like that enforced not only for those who post but also a prohibition against ad homnem attacks against candidates.
Much of the rancor has been stirred up because people call a candidate or politician a name or make some wild-eyed accusation, and then that candidate's supporters take offense and retaliate.
It does not advance the discussion to call Romney a RINO liberal, Guiliani an abortionist, Hunter a knuckle-dragger, etc. All it does is cause more ill-will.
I also would suggest that attacking the President doesn't help things. He is making decisions based on the information HE has, not the opinions of people on the internet. Name-calling only serves to alienate his supporters and embolden the left, who think that comments like that mean that they can win with their divisive strategy.
To my mind if you can't criticize without name-calling or promoting an alternative idea, you really belong somewhere else.
This site needs more reading of the article and comments, more thinking about what you have read and less posting.
While not perfect, I think a posting limit would do just fine.
