Atwood refused to accept the science fiction label for a very long time. Le Guin is much kinder to her friend than Atwood was in person to many folks about this (this is harder to cite because older convention and genre drama doesn’t really show up online, unlike modern). In recent years, Atwood has accepted speculative fiction (the umbrella term for lots of stuff including SF) because it’s convenient for her and helps sales. She was and imo still is a huge genre snob. Don’t get me wrong, Atwood writes great stuff. She just hates a lot of her audience.

Why do I care? Compare and contrast her to Vonnegut, whose agent wouldn’t let him use the science fiction label but actively attended conventions, telling fans he wanted to be SF but the money folks wouldn’t let him. Octavia Butler is equally fantastic as is Atwood’s dear friend Le Guin. Both love SF and are happy with the label.
