Will Bunch has a column about American fear of “The Other.” I agree with a lot of his points, but not that this iteration is somehow uniquely dangerous or unprecedented in American history; but, then, he has a book to sell on the topic, and I don’t.
He suggests, it’s not the “Mosque” or Obama in particular that have people riled up, but a fear of the other. I tend to agree. I think the tendency to divide the world into “in-groups” and “out-groups” is pretty well hard-wired into humans. The ability to define the group characteristics seems to be pretty flexible, however; and the wall between the groups becomes more rigid as the environment becomes more hostile.
I think, this time around, economic distress is probably the key factor in whipping up the frenzy against the “out-groups.” When the economy was booming in the 90s, I don’t recall all that much anti-immigrant sentiment, for example. I do recall more of it in the 80s and early 90s.
In college, I had a history course on British society in World War I and did a paper on attitudes toward people of German ancestry residing in the United Kingdom. As I recall, the attitudes that showed up in newspaper articles were fairly appalling, and there were even some internment camps. But the dynamic was fairly simple, the war created a distressed environment and people of German ancestry, whether loyal Englishmen or not, were part of the “out group.”
People are scared, and they’re lashing out at the unfamiliar.
