"I proclaim that X is Y and as of now, it's a truth that holds itself. We need to correct every broken mind to acknowledge this new self evident truth."

   But first of all take a deep breath. We're herding some sacred 
   cows to the slaughter right now. That's painful and bloody. TDD
   has been so successful that it's interwoven in a lot of 
   programmer identities. TDD is not just what they do, it's who
   they are. We have some serious deprogramming ahead of us as a 
   community to get out from under that, and it's going to take some 
   time.

Not a comment on the author, or on the general idea on tests (which I mostly agree with).
