I've always seen PoC in my SF/F fandoms. That's why Bujold's claims just made my jaw drop. She claims that history is inviolable, that it just happened and it's gone, then goes on to make a cognitive error that because she hasn't personally experienced encountering fen of color before the internet that they must not exist. She's attempting to write history by doing this. Now she's being corrected on that assumption, and thus her own perception of history needs to be revised. The contradiction is so inherent in her thought process.
