Marketers have long tried to turn happy events into shopping opportunities. Macy's and Gimbels and others pushed us to see Christmas as a chance to buy gifts. Shopping is right next to happiness on the spectrum of emotions, I guess, just as green is next to blue in the rainbow. They did it to Valentine's day and now, of course, Halloween.
Lately, some marketers would like to push us to move from fear to hatred. It makes it easier for them. We honor and remember the heroes who gave everything, the innocent who were lost, the neighbors who narrowly escaped. A day to hate? I hope we can do better than that.
