It wasn't the same student making both statements
Then surely that's just the case that different people have different opinions?
90-95% of published authors are white, only a tiny handful ever become the subject of a Twitter campaign or "cancelled" (and being "cancelled" rarely amounts to more than a few tweets, some people have received massive career boosts and received a huge amount of PR from claiming to have been cancelled), so clearly the current situation is perfectly fine for the vast, vast majority of white writers who write anything they like and don't get criticised for it.
I don't know why we're acting like this is a major problem, when evidently there are thousands of white writers happily writing books that are exclusively about white characters without any criticism, and thousands of white writers writing books about minority characters without any criticism?
Writing, and also giving preference to "diverse" candidates in other employment areas.
But that's obviously not the case when the overwhelming majority of people working in publishing are privately educated and white British, 90-95% of published author are white, and overwhelmingly male-dominated to boot.
