Sad thing is you hardly ever have circumstances where all people involved in the discussion are willing and able to keep t on a logical level, don't want to be right AND are willing to enhance their hiirizont (even so it might involve to shit their point of view. That doesn't mean you have to change the believe of any person taking part in the discussion, but nevertheless brighten everyones live and is alue initself by that.Fanaticism almost always denies facts and logic, and atheism isn't immune to fanaticism, just the contrary.
(I can only remember to have that once in a debian form IIRC).
Oh, and sometimes that also means that "We might never know for sure" (but respect everyones different point of view/believe anyway) as an "result".
