: : One often hears 'lightning rod' in describing the attraction of vigorous or violent controversy, as in, for example, 'His comments made him a lightning rod for all sorts of vitriolic invective'. This is interesting only in that the expression derives from the widely held but erroneous belief that a lightning rod is a device designed to attract lightning - ostensibly thereby to save other, more valuable objects in the vicinity.
: : In fact, a more opposite function obtains: The lightning rod actually drains off static electricity from the object it protects, making it unlikely that enough charge will accumulate to initiate a strike. Think of this: If a lightning rod truly attracted lightning, why on earth would you want to put it on top of your barn? Wouldn?t it be better to place it off somewhere by itself - close but out of harm's way, where it could 'attract' lightning without burning down the barn?
: : So taken literally, the example above ('His comments'?) should mean that the individual's comments served to 'drain away' or render less likely all sorts of invective.
: Interesting. That's what I assumed -- that the rod attracted lighting and then it was discharged harmlessly down a wire to the ground.
: Kudos, never thought about it before.
