I'm not sure if i would go so far as to say that there is a conscious crusade mentality here (of course it cuts both ways and i think we should be careful not to turn this into a crusade against DWB) - i think that many believe that they are acting "lovingly, with righteous purity and with peace of mind", but i do think that there seems to be a certain amount of blindness here.
