The answer is, of course: none of it was "grease." It was superfluous to you, but would not have been superfluous to others. A public comment intended to be read by many people on a blog expressly aimed at effectiveness in all regards, including communication, requires comments to be constructed robustly and with an eye to alleviating misinterpretation. Failure to do so is failure.

If you don't agree, then do please consider there are other people than you reading it and that you may be incorrect.
