Queer ships/queer readers vs het ships/het readers
I saw this post in the Dramione subreddit where they were talking about what other ships they read, and I was surprised by how heterosexual the pairings were. Hardly anyone mentioned Drarry, which seemed like the obvious one to me, or any of the big queer ships, and then the community was talking about much more peripheral hetero ships like Hermione/Theo and Draco/Ginny.
What do you think? Do queer ships like Drarry and the Marauders pairings tend to not draw straight readers?
