I don't think it's as harmful as you seem to
A very slightly harmful instance of a phenomenon that is moderately bad when done on things that matter.
I thought you might handle this situation like this and I mildly disapprove of being this aggressive with this tone this soon in the conversation.
Where 'this soon' means the end. There is nothing more to say, at in this context. (As a secondary consideration my general policy is that conversations which begin with shaming terminate with an error condition immediately.) I do, however, now have inspiration for a post on the purely practical downsides of suppression of consideration of rational alternatives in situations similar to that discussed by the post.
EDIT: No, not post. It is an open thread comment by yourself that could have been a discussion post!
Compare and contrast my(September 7th, 2011) approach to yours(September 7th, 2011), I guess.

ADBOC, it didn't have to be.

If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
If continuing the discussion becomes impractical, that means you win at open threads; a celebratory top-level post on the topic is traditional.
