CMV: There should be more minority characters in movies/TV that are villains.

Whenever the topic of minority representation comes up, it primarily talks about protagonists or hero representation. That's all well and good, but eventually we'll have to talk about the flipside of the discussion. 
Of course we have had great villains that were minorities (ex: Killmonger, dang what a great villain). 
But at least from what I see, most villains (especially in action/superhero movies) either boil down to "calm and collected British bad guy" or "evil Eastern European guy."
It may be that studios are afraid to cast minority characters as villains. The key here is the two camps of minority villains.
One camp I call the "Killmonger camp", where the villains motivation is directly tied to their minority status, and that is purposely portrayed to be in at least a sympathetic light.
The other camp is the straight up villain, that just happens to be a minority. Take Dr. Wu from Jurassic World, or Black Mask from Birds of Prey. Black Mask is a brutal gang boss who enjoys cutting people's faces off, and also happens to be gay.
As the discussion of minority representation in movies increases, why not give Blacks, Asians, LGBT, people with disabilities fun and scene-chewing villainous roles?
This is isnt a big issue, but I feel like it's at least worth talking about.

That is one of the basis of the theory of accurate minority representation. According to a 1969 article by Cedric Clark, there are four stages of representation:

-Non-recognition: the minority is not represented and do not appear significantly in the media. Transgenders are there, only a handful of shows have transgender characters.

-Ridicule: The minority is shown as a subject of mockery and only exists in comedy. Gay people are mostly there, but it's starting to evolve toward the next step, 

-Regulation: The character is shown in socially acceptable, generally model or idealized roles. They almost never play villains. Here you can find women, black people.

-Respect: The minority is cast in all roles and as deeper character, on par with the majority characters, and can actually be good or bad. The characters are more real than just stock characters constantly used, and can be villains. Here you can find white "minorities," eastern europeans, Irish, Italians - mostly people that used to be minorities but are considered white now.

So the endgame is indeed more villains being from minorities, but some still have a long way to go before we reach that stage, and it's unclear what happens when we skip steps - a lot of people have been outraged by a transexual villain, recently.
