Unpopular opinion: not everything that makes you uncomfortable is bad. Sometimes discomfort means your worldview is being challenged. It’s okay to sit with discomfort and think about where it’s coming from.
It’s actually completely ok to be attracted to a fat person because they’re fat. You’re not inherently disrespecting them by not ignoring and actively appreciating their fatness. You don’t see the same level of scrutiny towards people who have preferences about hair color or height or facial hair. Having a preference doesn’t mean you dehumanize people who have the feature you’re attracted to.
When you’re not forcing them to do or be anything they don’t want to be, there’s nothing inherently immoral about being attracted to specific physical traits.
Stop treating fatness as a trait that people are attracted to other people in spite of. Stop treating fat people like they’re undesirable and any attractions towards them is inherently suspicious. Especially if you’re acting like this is somehow for the benefit of fat people.
