I for one don't care about your delicate sensibilities. The media you are talking about is designed to be inclusive. Perhaps a white man is not the main character for a change. Personally I prefer white men as protagonists because I am one. I am used to it. It's strange to have a female Dr Who. After all, women are supposed to play an inferior role. That is what I like. But at the same time I can understand other peoples points of view. Unlike some, I have the ability to feel empath for others who aren't white men like me. Sure, during a boxing match, I am secretly hoping that the Irish fighter wins against the black guy. But I won't bet on it, because I know that it's a pipe dream.
Anyway, culture IS change. It has always changed. A culture that isn't inclusive isn't worth protecting. If our precious white culture becomes a minority, then it will be protected by the same inclusive culture we helped build.
I for one, welcome our new SJW overlords and would like to remind them that I might be bisexual, depending on whether or not traps are gay
