No, I understood. The thesis is that the great writers were affected by the war and changed American literature. I say that's bullshit, too. War is war. It's been hell forever and the subject of great stories forever, too. What authors write today is no different because of something that happened 150 years ago.
I commented on a particular statement the writer made. And no offense, John -- I'm smiling now -- but when people start talking about realism and romanticism movements in literature, my eyes start to glaze over in the same way. :-)
