Every few years i learn something awful (misogyny, racism, queerphobia, eugenics, etc) about another white, usually male, SFF author who I read in my callow youth (OS Card, HP Lovecraft, W Ellis, JK Rowling, etc)
Lately, my best source for these unpleasant revelations has been The Midnight Society, as in this one for Dan Simmons

At this point I'm not really willing to stan for white straight dudes in SFF; imma wait for them to die before canonizing (IM Banks).
