Is it wrong for Caucasian actors to wear makeup to appear Asian (or black)?

The article presents an incoherent mixture of perceived insult, lack of Asian role models on TV, and loss of work for Asian actors. Any or all of those issues might be valid, but they are all different, and mixing them up produces only confusion.

If it is a matter of work discrimination, how about making up nonwhite actors up to appear Caucasian? All actors' race would cease to matter.

If it is a matter of visible role models on TV, that's a matter of appearance only. Why does it matter what the actor's real skin color or appearance is, beneath the makeup?

If you feel insulted, please explain why an actor's makeup constitutes a statement about Asians, because I don't see that.
