Maybe Jim could set something up like the religious Square where pretty much you have to have a thick skin to tread there..... It gets hot and heavy but you sure learn and see the difference between truth and falsehood when all is said and done. It's moderated... basically you can't make it personal attacks...but it gets feisty and lively none the less. I rather think Paul and some of the disciples had some heavy debates along the way and a passions rose.....so too with politics as religion....passions run high.... there is much at stake to win or loose.
The standard for manners in a Screaming Liberals forum would need to be far more tolerant. There are going to be F words and worse slung around. These are the dwellers of DU caves. Look at Townhall. It has a lame and weird bowdlerization system (one of the things you can’t say is jackass) but it’s trivial to get around by embedding punctuation or spaces in your naughty word.
