Machloket
מחלוקת
Sephardic pronunciation: Makh’-LO-ket. Ashkenazic pronunciation: Makh-LOI-kess
1. A division of opinions, potentially highly productive under conditions of mutual respect and open communication.
2. A discordance between personalities, rendering them incapable of seeing eye-to-eye or working together, ostensibly supported by some rational justification, but ultimately driven by ego and self-concern.
3. A highly destructive disease that infects a community or society, factionalizing its members and dissolving natural bonds, capable of triggering a state of catastrophe and exile for almost 2,000 years.
4. Hell on earth.

As our world has slipped away from acknowledging Hashem and has rejected His user's manual - i.e. Torah - we have slipped further and further down on the lsit of the definitions of this word. It is instructive, to me, to remember that "Hell on earth" is #4, and to consistently treat others with respect and dignity - regardless of their points of view or their particular passions. I am reminded of a very wise person telling me, "Would you rather be right or happy - up to you".
