I find that one of the real challenges here is that people have different agendas and different understandings of argument, debate, discussion, etc. Sometimes verses are hauled out as triumphant refutations or confirmations of some point and yet to the dispassionate observer there is no necessary connection between the adduced text and the point it is supposed to support.
And there is little appreciation for the different sorts of proof possible when different sorts of things are being considered. There is less ability to turn back and examine an argument and determine what its rules, tacit or express, are.
And then there are people here who do not intend to converse. They deal almost exclusively in blesses and curses. Either one agrees or one does not.
These latter sometimes seem to follow the school of "If you did not agree with me, it MUST be because you did not hear me." So they say the same thing again and again, maybe a little louder or more confrontatively.
All this passion, little skill and less desire for negotiation. No wonder it's a scandal!
A lot of truth to that.
