The "best answer" (IMO) to this thread was inadvertently dropped in another - condescending.
So many threads break down into this as of late (if people have any restraint), but some come right out of the chute on that foot with the thread title/OP. Then it becomes some childish competition to see who can dredge up the most dirt/BS (foul language *intended*) to validate their (often irrelevant) point. The "Holier than Thou" mentality is not decorum I expect in ANYTHING "professional" (in any industry), so those who step up to the plate with this attitude must realizes it implies the exact opposite. My reaction has always been intense sarcasm (usually to divert elsewhere), but even that still fuels some to jump back into this fray (some have predetermined this path for themselves, and there is no stopping them).
Food for thought anyway... I was trying not to post to this thread (since the truth often hurts), but realized that I inadvertently commented from my phone and am now "linked" to it anyway (ugh, the ironies in life). At least I got that off my chest
