Sure, it might be relatively weak, though I think it does have a large basin.
And my point was that even a “friendly”-attractor AI is still a large x-risk. For example, it might come to realize it cares about other things more than us, or that its notion of “friendliness” would allow for things we would see as “soul destroying” (e.g. a Skinner Box).
I don’t think this is due to a pro-diversity bias, but is simply due to this being extremely popular in easily available stories: https://archiveofourown.org/works/68352911/chapters/176886216 (9 of the top 10 pairings are M/M, each with 40k+ stories; for reference Project Gutenberg only has about 76,000 books total). I think this is due to M/M romance being a superstimulus for female sexuality in a similar way to how lesbian porn is a superstimulus for male sexuality.
The pro-diversity bias’ main influence seems to be changing the proportion of stories focused on non-white male/male pairings, as you can see here: https://archiveofourown.org/works/27420499/chapters/68826984
