Now that I finally read the (closed!) thread that was refered to in the OP, I can chime in, too. While my decision of which sock to pull out of the drawer was not based on weighing any Torah sources, even if my desire to choose correctly would be because of a Yiddish reason had I been on that level; when someone asks what is the “correct” thing to do we would most definitely look to the Torah for guidance. In that other thread, the discussion was actually about an Halachic concept, which really makes aries’ remark puzzling. I think aries was just caught off guard, not expecting the conversation to take a turn away from being a friendly opinion chat.
Once we’re on the topic, why do so many people keep on saying the mantra, “Ask your LOR”? Sometimes threads get closed with this mantra posted on the gate. Is there really something wrong with discussing Torah? Would you now call out in all Yeshivos, “Rabbosei! Stop! Why are you all saying Svaros? Go ask-your-LOR”?
