TOI:
You are completely wrong, and dangerously so.
There is no such thing as a “chumroh” to drink to shikrus on Purim. There is discussion about what the nature of the mitzvah is. And many, including nearly all of the poskim that are the leaders of our generation, are stating clearly that the drunkeness that is involved in so much danger (alcohol poisoning, accidents, getting rowdy and fighting, drunk driving etc.) is not the preferred way to go, and that the mitzvah does NOT include these negatives. I consider ????? ???? ????? part of the mitzvah, and will be careful to avoid getting stuck in trying to fashion halacha to be consistent with my taavos. So no one is failing to adhere to your invention of chumroh.
