If the intent here is to raise awareness in people who behave badly well, good luck with that--i've already seen in this thread that some of the worst offenders have no clue that this thread might just apply to them. It would seem that arrogance is blind and perhaps these offenders really don't see themselves in that light--which means the problem will remain.
To a certain extent this, and other forums, represent the sentiment of the country/world and times--there's enough diversity here that you get all types. In the six years i've been a member i've definitely seen the tone change for the worse but not extremely so--it's usually just a few prolific people--and sometimes, if you wade through the condescension, they actually have something to offer. I'm kind of in agreement with those who think the problem is not really that serious. I still enjoy reading the weekly summary and i know whose opinions i will value and those i will ignore--and it's not always the arrogant ones i ignore--as with any forum there's the good, the bad & the ugly so i don't take it that seriously.
Merry Christmas/(or if applicable Happy Hanukkah ) to all and Happy New Year
