Correct me if I am wrong, but I have looked back over this thread and the only mention of the word 'arrogant' seems to have come from yourself.......
I don't believe that any of us even alluded to arrogance.
As for looking for "an equally strong list of reasons.." does it really have to be only 'strong' before being considered..?surely, the whole is normally a sum of the components?..like respecting your fellow men and their language.
