Maybe Why We Ought to Study Art...

Because it helps explain contradictory beliefs that are nevertheless coherent--

Because all of this is simultaneously true: 

In the past, casting White actors as obviously Asian characters or Native American characters was pretty ludicrous and punctured our ability to suspend disbelief.

We are making a similar mistake today by every show and movie having a diversity mandate, so Black characters pop up in premodern England, every show features a gay romance, and Pam Anderson had an Asian friend (no way). 

And yet, I'm excited about James Franco playing Che Guevara and Ana De Armas playing Marilyn Monroe.
