There is a fundamental error, rather common, much more so since the internet became nearly universal. Chilul Hashem is NOT defined by publicity. If something negative does become public, the chilul Hashem has just been spread. But the issue exists regardless of whether it is public, private, or top secret. If anyone wishes to question this, I refer to the Mishna in Pirkei Avos (4:4):
המחלל שם שמים בסתר נפרעים ממנו בגלוי.
Clearly, the chilul Hashem can occur without others knowing. If it was secret, how did it qualify to be chilul Hashem? If something negative can be discussed, the forum or amount of attention is immaterial. Does anyone wish to disagree with this Mishna?
