I just scanned the writing in question. Yes, it's a bit over the edge, IMO. In the writing I see, the OP is called 'hopeless' and is told he has a chip on his shoulder. Something in the post was called 'pretentious'.
So that's enough for me. I know the moderator tm_member pretty well, and he and I agree on the tone we're looking for in the forums, so I respect his judgment (and agree with him in this case).
I realize this sort of exchange occurs regularly online elsewhere, but I just don't like it or want it here.
