It's funny how "preference" is something that is inherently tainted by bias. I went from not thinking fat people were attractive (believing it was nothing bad! I don't think anything bad about them! "I'm just not into them!") to, after years of healing my relationship with food and reframing how I feel about my body and educating myself about fatness and what fat is and what it isn't... suddenly I was very attracted to fat bodies. Not in a dehumanizing way, but, wow, that's a gorgeous body, framed by hills and valleys, dips and waves, a body that demands all of my strength and devotion to lift it up, a body that I have to dig under folds to fully landscape.
I can wax poetry about any damn body of any weight and size and height, damn it, but the fact that I found it in me the ability of waxing poetry about fat bodies when I worked on my own bias, the fatshaming that was drilled into my child body, a body that was put through so many diets and weigh loss fads that I could dig my fingers under my own ribcage like a party trick, tells me that "preference" oftentimes is a code word for "I learned I shouldn't see this body as a good thing and my neutrality hides something deeply embedded into my brain"
