I don't understand why some people are struggling with this.
Any person who immediately gets angry and posts vehement complaints, when a minority lands a role that was previously played by a white person, or a role at all, should be put into the same box. Bonus points if they throw in that it was done to please SJWs and all that shit.
There is no rationalizing to be done. Why are they up in arms that a minority got a job? Why is the race of the character a hill on which to wage a battle? Why do they always point to this as a growing and negative change in society? Why is their reality literally threatened?
Remember when the little black girl in Hunger Games got a job? Were you are any of your friends/family mad about it? In the box you go.
Racism really isn't a complex thing to understand. This is the same damn violent reaction we got in the Civil Rights movement. Remember when it was the end of society, because black kids were going to be allowed to go to white schools. Draw a direct line to matters like this, and judge the perpetrators accordingly.
End of.
