You are putting words in my mouth I never added ill intentions to anybody. I never said “lied” or “doesnt make sense”
Here is how I would phrase it:
holy members of klal yisroel stopped duchaning, we do not know exactly when or why, and later generations gave reasons to expalin the existing practice, even if the reasons given are a stretch.
Are you saying the Rema went through the sugya of mitzvos tzrichos simcha. Came to the conclusion that it was meakev (but only for Birchos kohanim) and paskened that therefore we shouldnt duchan in chutz learetz? (Ive asked variations of this question, Im not sure why you are having a hard time responding and instead are attacking me)
