dskira,
Kindly do not confuse "freedom of expression" with "permission to post unmitigated bashing and criticism".
Secondly, while
you might not know who K1W1 is, others here do. A screen-name only offers anonymity if people don't already know the person face to face. Also, as far as I know, K1W1 did not introduce himself as an expert within minutes of deciding to contribute to the forums. Humility... you might give it a try.
Lastly, please take a moment to read the
Forum Guidelines, to which I've provided a link. If your attacks continue your posts will be removed.
