Catch Yourself: I have yet to meet a single person who does such a thing despite the fact that I have lived in many communities and met hundreds of Orthodox Jews of all types.
As you wrote, “Without question, most Orthodox Jews are horrified by the thought of such practices, which are in direct opposition to Torah and Middos Tovos.”
Of course, Am Yisrael is not perfect and we have to continually work on ourselves. The best way to do that is through positivity and not negativity. We can best accomplish that by speaking positively of other Jews and spreading the MANY THOUSANDS of positive stories instead of harping on the occasional possible negative story. We can accomplish this by “judging others favorably” and not jumping to assume the worst.
The Bais HaMikdash will be rebuilt when we stop speaking badly about others (or to follow my own advice and speak positively – when we start speaking positively about others)
(question: why does my spell-check like the word “negativity” and not “positivity”?)
