NY Mom is correct. Without knowing anything else about Joseph’s point or purpose, the OP is divisive. That Joseph is merely quoting others who state true things doesn’t make it any less divisive. Would it be any less divisive if someone were to quote true news articles about improper activities that ultra-Orhtodox have been involved in, even if true, and even if just copies of things other people said?
I am not a kiruv professional, but common sense tells me that “here’s what you could do to improve,” is a better approach than “what you are doing is wrong.”
