it is impolite.
now, could you do us all a favour and read the replies to your post in the 607 thread? there were a lot of questions raised by your comment and i think it would be a good witness if you would at least attempt to answer them. two very important ones are:
who are the "celebrated WT scholars?" what are they celebrated for and who celebrates them?
what "secular evidence" is there to prove the 607 date?

P.S. when did JW's started celebrating ANYTHING, let alone humans?
