Well, whether or not your actively seeking out people from a marginalized community is the crux of your question here. Does it matter to you, no like, does it really matter to you the race/background of the creators of the media you consume? If it doesn't, than this question come off as you implying that black people aren't doing enough for themselves to make it in the industry, even though I assume that wasn't your intention.
I have to give my applause to @Shanny8 @Calculus_Homework and @DokiDokiTsuna for explaining the reasonings behind the how things are in the space right now (better that I ever could).
And while I can't say I have the right to condemn any of you, some of you are talking really loud without really considering all the factors that bleed into a lack of representation. You can point to numbers, you can point to luck, you can even point to access, and you can say it's probably not racism. But those are each shortsighted in their conclusion and should be considered plus many more factors. And also it is racism, always has been.
