A lot of deaf and hard of hearing people aren’t as literate as hearing people are. This is because the education system in the past did not prioritize teaching them to read and write. This has changed since then. Some deaf people are proud of their culture, to the point where some would prefer not to become able to hear, and will decline cochlear implants. They have a very tight knit community.
This I learned working for a company that provides services to the deaf and hard of hearing, as well as people who have difficult speaking as well.
