I work at a job providing services for the hard of hearing. While I can't sign, seeing rules for sign language in Golarion meant a lot and sold me on second edition.
I also really appreciate the paragraph
"You can use role-playing to challenge not only the norms of Pathfinder's fictional world, but also real-life societal norms. Your character might challenge binary gender notions, explore cultural identity, have a disability, have any sexual orientation, or any combination of these suggestions. Your character can live any life you see fit."
Thank you for explicit inclusion in 2nd e.
