This may be the story nobody in the media is covering
People who support the war are unable to discuss it with their friends for fear of losing them. The link above mentions Michelle from A Small Victory. And Sean at Everything I know is Wrong is apparently also feeling the hate.
It's sad but also illustrative of something I noted in the 60s and 70s. People who claimed they cared about peace engaged in some of the most hate-filled rhetoric and unpeaceful behavior I had ever seen. And it's happening again because the U.S. is responding to a hideous attack on our soil that killed thousands of people. Somehow, this response has been converted in the minds of the left into a replay of Vietnam, but far, far worse, because we haven't fought this war as a "police action" or limited war in the sense of Korea, Vietnam, or the First Gulf war. We have followed the World War II model established by FDR and George Marshall: defeat the aggressor and destroy the infection at its source, then help the corrupted societies to rebuild as democracies. Why this should drive the left so crazy is more of a mystery today than it was during the Vietnam era. Back then we had a draft.
