Avi K:
Let’s examine the halachos you cited. If we are in a state of needing to release pressure on someone, as in pent up rage, and we find someone talking in shul, we should be free to empty our wrath on that fellow. Correct? Obviously not. Whatever path we choose to enforce the decorum of the shul, it is about achieving the result of the shul being a place that shines in its kedusha, without the chatter and such that detract from this. So our focus is on the result. The means of how to achieve this are simply suggestions of these various Gedolei Yisroel that were appropriate to their communities and experience. The Mechaber (Beis Yosef) states גוערין בו. If you review the commentaries, there are several ideas proposed, and despite several that repeat or quote from others, there are varying opinions. The bottom line is that one needs to focus on the result, not the process. The public shaming is not a mitzvah of its own. It is simply a means to the achievement of the proper kedusha in the shul environment. If that shaming stuff yields a different result, it loses its “mitzvah” completely. Shul police is a useful idea, and it has been implemented many times in the current era. The yelling and shaming has not accomplished much, and is more likely to drive someone away from davening there or altogether. I would wish that not be the case, but my wish does not change reality.
I am not someone who favors talking in shul, nor am I ignorant of the halachos. Ultimately, the best outcome is the more people that are truly involved in tefiloh in shul, the better. At this point in time, there is far more to gain with “Praying with Fire” and “Praying with Meaning” than all the admonishment and punishments. Keep your eye on the goal. The terrain changed.
