Yep...you heard the man...."white folks."
Storch is dead on correct with that assessment. White folks seem to be less willing to cede a point or yield ground in an argument about ANYTHING.
It is, indeed, a cultural thing. One of the causes is our upbringing ....the way we are raised, and our personal view of our world and the people around us. Despite the protestations of some who see themselves as fair, sensitive and "enlightened" (both conservative and liberal ) we simply cannot bring ourselves to accept the thought that "I might be WRONG."
Because of our history of success we tend to be an arrogant race....and raise our children to be that way. That's why so many tend to see certain topics as having no "middle ground." Gun control, religion, race, sexual and behavioral mores are, as a result, extremely volatile issues.
And...so...our egos and arrogance come into play. One can see evidence of it on almost every topic in which religion, culture, and politics are discussed.
I admit it....I'm guilty of it. It's hard not to be guilty of it when one's culture and beliefs that you grew up with are being derided and belittled by some faceless denizen of the internet.
As a result....the restaints of civility come OFF.
