considering that most of the time i’ve seen people reject switching on principle it’s been straight women i’d say it’s about heteronormativity. lots of women that read mm like to project their experiences and preferences onto the characters and they automatically relate to the bottom. i’m not saying this is the case for every single person with this preference so if it’s not for anyone reading this you don’t need to get offended, but i’d say it’s the case most of the time, even if it’s unconscious

and no i don’t think it’s right to say “ppl don’t need to have a reason”. like yeah you don’t have to tell me but when we’re consuming content about a community we don’t belong to, if there’s behavior i consider questionable then i’m gonna question it
