Actually I think both sides do a pretty good job of that. Your own question in fact fits the bill with statements like "most media don't repeat the Republican lies about Obama". The problem is that not all statements about Obama, his associations, records and proposed policy are lies. However, every Obama supporter and most of the media deems any questioning of the man as lies, racism, or propaganda. From what I have seen Obama supporters will not critically examine the man and oppose any efforts from those who do. I don't care who anyone supports, I would just like to see honest criticism and honest reporting. So sit over there and wrap yourself in smug feelings of how correct you are in your own mind, but understand that not everyone shares those feelings and it will be a fight to the end no matter who wins. Lastly, examine your first two answers and then come and try to tell me how Obama supporters engage in lucid, or productive discourse because frankly I just don't see it from most of them.
