Communication, at least to a moderate extent (sarc), demands that to achieve a moderate position by all parties concerned they must have the means to at least explore the 'isms' by example because without opposing extremes either the moderate is never explored or never known. The key to moderation is to know and explore the extremes, the isms. In addition, without the extremes being known, evolution would be unnecessary. Hurrah for the extremes and the isms, hurrah for conflict, they gave us 'fight or flee' and the intellect to overcome obstacles.
