“That video is an extreme example, presumably taken at a yeshiva without supervision, rather than a shul. As someone commented on the article: many would fulfil this minhag by half heartedly throwing a towel or two, not the litzonus and disregard for safety shown on that particular video.”
This is a good point.
I’m not making any comments about the video or the minhag, but if someone would put out a video of the stuff that goes on in some shuls (including litvish shuls) on Simchas Torah, I’m sure many people would have similar reactions.
Maybe we should abolish Simchas Torah?
