Rabbosai, enough! There are gedolei poskim who discourage excessive drinking, let’s remember who we are!
The reason many rabbanim today discourage excessive drinking on Purim is because there are many, many communities where people, particularly young people have developed life ruining and life ending addictions. This started for many, including a good friend of mine, on Purim.
This is not trying to be meikil, it’s trying to save lives.
Personally, I drink but as per my Rebbe’s minhag, I only offer liquor to married people who are “holy” drunk, not wild drunk. When my son’s pass bar mitzvah age, I will likely switch to a cup of wine and a nap, because I don’t want to set the wrong example.
This is not a joke. Addiction is everywhere, even in the most special and holy kehillos.
