what to do about flame wars? well what does your mission statement say?
you can't make a omelet with out breaking a few eggs
so why do you think you will make an effective change with out ruffeling a few feathers? the fact that you are seeing this level of defending one's belief is a good thing if you start to "edit" this sight you might as well just take it off line as you have failed !
so make them stay on topic and --- let them blast away!
this is how social change takes place! it is not always nice and fluffy
