A Purim thought

This past Shabbos, a certain R' Reider spoke after mussaf regarding "chayav inish liv'sumei ad d'lo yada bein arur Haman l'varuch Mordechai". He asked the usual questions on this statement in Megillah and proposed (I don't recall his source, if he quoted one) an interesting reading. In the world around us, there are certain things that are clearly evil (arur Haman) and certain things that are clearly good (baruch Mordechai). Additionally, there is a large grey area made up of matters in which the two polar opposites compromise - this is what is 'bein ahlv"m'. When one drinks, one becomes bolder and less able to see shades of grey, and his opinions polarize. On Purim, one should drink to the point that he no longer feels the need to compromise his beliefs regarding what is good in the world, so that he truly does not see what is "between" Haman and Mordechai; either something is good or it is not.

I'm probably missing some fine point of what he said, but it's still an interesting point to keep in the back of one's mind.
