an obligation to get drunk? That is stupid. Kids too huh?
Someone obviously didn't read the link I provided. Read first, open mouth and make a fool of oneself after.
The Rabbi's who have commented on this over the past two thousand years have studied the issue from almost every side. These were people who are not inclined to brook silliness or even abide by a practice that is not of significant meaning past their time, hence they forbade the practice of polygamy more than 1000 years ago. A ruling that has gained acceptance and general agreement in the following years. The Rabbi's looked at the Purim celebration and the obligations surrounding it and assigned significant religious significance worthy of demanding excess when almost every teaching for every situation instead insists on moderation and fences around fences to prevent immoderate behavior to rise to the level of sin.
Rather your snap judgement that something makes no sense is built from ignorance rather than seeking an understanding of this seeming paradox. Strikingly, you should also remember that this obligation falls only upon Jews, so if this doesn't include you, you need not worry. How cool is that! But, alternately, much of what is written in the Bible is universal, so perhaps the meaning of this may be of value even to someone who is deeply suspicious of such things.
