Publishers need to be able to sell their books.

And there's a lot of avenues for self publishing and self marketing these days. If there were really so many genius black authors being oppressed by whitey than maybe we'd hear about more of those, huh?

Maybe there's just not a lot of good black authors. I'm not screaming discrimination because hip hop is disproportionately black. Or demanding that we need more white representation in rap. The most likely answer is that black rappers are generally "better", or at the very least more marketable and profitable.

You see where I'm getting at.

And what you said about female authors is ridiculous. Maybe in the past, even the recent past, sure, I don't doubt that there was some discrimination against female authors. But it only took me a quick Google search to discover that women dominated literary bestsellers in recent years. Plus there have always been influential female authors. Mary Shelley arguably invented the science fiction genre for example.

Probably because their writing is trash lol

Because white people made both genres and have contributed the most to both of them?

There's nothing stopping black people from writing science fiction or fantasy based on their own people and culture, they just don't seem to do that very much.
