Drama demands conflict and suspense. But Conservative are just as creative as any Liberal loudmouth who wants shock value to pass as entertainment.... Conservatives, especially judging from some of the posts I've read on this board, are very creative. In fact, all great artists have been artists of the right... can't think of one from the left except maybe Brecht.
Surely you jest? Tennesee Williams, Oscar Wilde, Charles Dickens, Henry David Thoreau, Ralph Waldo Emerson, Ibsen, Norman Mailer, Truman Capote, the Bronte sisters, and many many more that I could name were anything but on the right.
I have a pet theory that conservative personalities are anethma to the inherent instability of a career in the arts. Conservatives are attracted to professions with more predictable futures and incomes.
