The “ask your LOR” response is something I’m still trying to understand.
For personal issues (marriage, family, employment, etc.) it makes sense. It also makes sense for matters of halachah that can vary from place to place (kosher food standards, validity of an eruv, etc.).
But why should one have to ask his LOR whether a particular kind of tallis katan is acceptable? Why can’t a minimal standard be generally accepted by Jews everywhere?
