Here's a quote from Brokeback's producer that best sums up my point:

"Once people saw the film, they understood that it was a film about a kind of epic greatness that can exist in anyone, anywhere, no matter who they are, no matter what their sexual orientation or class or historical circumstances," said "Brokeback" producer James Schamus.

Of course, I am not denying that the main characters are homosexual or gay. What I am saying is that there is a greater message at issue: that all Americans can be a type of ancient Greek hero, like Achilles, if our establishment helps to clarify what is really important in life (through movies such as "Brokeback" and a classical education available to all) and, ultimately, if we have the courage to try.

Now I am utterly exhausted and will go back to pontificating about how brilliant Liza is in "Arrested Development".
