That's the interesting thing. Whenever we object to a non-white actor playing a white figure they obviously are NOTHING like, the "fans" of the stupid casting are quick to pull the "you're just racist and want to see straight, white males in everything"
But when we're JUST as adamantly against a white actor playing a character who is SUPPOSED to be a minority (again, Benedict Cumberbatch as 'Khan Noonien Singh'), we get the silent treatment.
And I'm sorry, if the musical was so "good" and stood on its own merits, it wouldn't need to resort to gimmicks like this.
Now, I just sent Impy a post the other day that I finally gave the politically correct "female Doctor Who" a chance, and I enjoyed the episode and was presently surprised by it. But I'm not going to pretend its must-see entertainment or the fact the actress pulled it off doesn't mean changing the character's gender swap wasn't motivated by rampant politically-correctness and she "just happened" to give the best audition for the role. We all know why she was cast, and the reality is that Doctor Who has seen better days.
