^The fact you think this says more about your own thoughts. The movie brought in some scenarios from the other two books, like the riots in District 11. There were a mix of ethnic groups during the Riots. Even in today's society if you were to pick two random people from certain towns or cities the chances of them both being from the same ethnic mix is significantly high. The district is a town. It stands to reason that any given District would have a higher percentage of a single cultural background.
Also, there was a huge multi-culture thing going on in the Capital. The Capital and District are the remains of the United States. Today black people only make up 13% of the population with white people at 72%. The book is true to current statistics.
I never once thought Rue was white. She mentions multiple times she is dark skinned in the book.
As for the tweets, I think it's irresponsible of that Website to be finding the worst tweets about a movie then writing an article about it. They had nothing of significance to add to our society with that article. If you start searching the internet, it's easy to find trolls, bigots and people looking to excite others through their words.
The biggest problem with the movie is that it was turned into a love story not about children being forced to kill other children, and the poverty the other districts were made to live in.
How in the world did skin color conversations even happen? Or right, all it takes is for a single troll to say something about white vs black people and the internet blows up.
