There has long been a penchant among pundits and culture hounds to opine on the root causes of Hollywood Liberalism. There's a myriad of self-serving explanations for why entertainers are usually liberal (they're pandering to the worst impulses in society to make a quick buck; they're stupid; they're "limousine liberals" with unresolved, success-induced guilt; etc.). Now, I’m not a politician or a statistician or a scientific personality – I am not, therefore, subject to the same professional constraints that prohibit them (and others) from lacquering bold and entirely unsubstantiated claims with the kind of sophistry that makes theory look like fact. In addition, I'm a crackpot liberal blogger who works in the entertainment industry. Why all the liberal celebrities? I'll tell you: Natural Selection. Recall the early years of Rush Limbaugh and the famous rhetorical red herring, "Political Correctness". Limbaugh confidently (and incessantly) declared that "liberals have no sense of humor". He joked, he guffawed, he swallowed whole chickens in a single gulp: America was entertained. For awhile, it became the accepted wisdom that liberals (i.e. Mac users) were not fit to entertain – only to whine and quaff wheat grass. But, as it happens, this was only a statistical anomaly in the evolution of entertainment. Hollywood is growing ever more liberal because show business is a hostile environment for Republicans. Contrary to conventional wisdom, the incessant demand for fresh content (for television, film, visual art, literature, etc.) has created an environment where the following are rewarded: dynamism, extremism, curiosity, flexibility, confrontation, and adaptability. Do conservatives posses these qualities? Sure. But not nearly to the degree that liberals do - at least insofar as art is concerned. Liberals, Independents, and even Libertarians are better suited to artistic endeavors than rock-ribbed, Bible thumping, moralizing conservatives. So while there are some excellent examples of right-leaning content in entertainment (i.e. South Park, The Simpsons), conservative entertainers can only respond to their liberal colleagues as the ocean responds to the moon.
