Sign language is the most important instrument for communication between deaf people and the Deaf culture. Using sign language deaf people can join social networks, local and globally, which join the Deaf culture together. Sign Language is a loose term for people that are deaf or hard of hearing and use signs to communicate. American Sign Language (ASL) is most closely related to the older form of French Sign Language, as Laurent Clerc, who was deaf and a teacher, was brought to the America's by Thomas Hopkins Gallaudet. Though Clerc brought French Sign Language, there was already sign language being used. Martha's Vineyard had more than average deaf people who had created their own Martha's Vineyard Sign Language. The French Sign Language and the Sign Language that was already in use, became American Sign Language. Deaf and Hard of Hearing communities are closely drawn together due to their culture and use of Sign Language. Sign languages, like the English language, are always changing. In the United States there are many varieties of Sign Language - from SEE sign (Signed Exact English), which follows English grammar rules when using modified ASL signs, to the Rochester Method, where every single word is finger spelled out in the English Language, generally without the use of signs. There is a grey area in between 'English' and 'ASL' known as Contact Variety (previously referred to as Pidgin Sign Language, or PSE), which uses any number of combinations of English word order/grammar combined with aspects of ASL (or SEE).

Another powerful bonding forced in the Deaf culture is athletics. Athletics open up a path to achievement where many others are shut out by prejudice due to the level playing field of certain sports. Athletics also create many networking opportunities for Deaf people across the United States to expand their social circles, due to the increased mobility that results from out-of-state competitions, because the deaf population is considerably small at the local scale.^[3] Deaf people participate in athletic activities to cultivate their cultural identity as Deaf people. In athletics, they can find solidarity where they are able to comfortably communicate with one another without barriers, embrace values and social norms natural for them and distinct from those in the hearing community, and allow for Deaf people to participate as coaches, athletes, and participants.^[4] The American Athletic Association of the Deaf (AAAD) is huge help for deaf people by representing Deaf clubs and organizations throughout the entire American states.^[5] The impact of sports in the deaf community can also be seen on the international level. The Deaflympics, sanctioned by the International Olympic Committee, are an elite international sporting event where deaf athletes from across the world compete against each other quadrennially.^[6]

Plaintiffs challenged the refusal to provide an interpreter on a variety of constitutional and statutory grounds, including the federal Individuals with Disabilities Education Act ("IDEA"),^[69] its Arizona counterpart,^[70] an IDEA regulation,^[71] the Arizona Constitution,^[72] and the Establishment and Free Exercise Clauses of the First Amendment to the United States Constitution. Plaintiffs successfully sought relief from a federal district court, which concluded "The service at issue in this case is part of a general government program that distributes benefits neutrally to any child qualifying as 'handicapped' under the IDEA, without regard to the 'sectarian-nonsectarian, or public-nonpublic nature' of the school the child attends". In a 5–4 decision, the Supreme Court reached the same issue, but reversed on the merits, finding that if it provided an interpreter the school district would not violate the Establishment Clause.

UPS (begun in 1999) was the first equal opportunity employment class action brought on behalf of deaf and hard of hearing workers throughout America concerning workplace discrimination.

1. UPS failed to address communication barriers and to ensure equal conditions and opportunities for deaf employees;
2. Deaf employees were routinely excluded from workplace information, denied opportunities for promotion, and exposed to unsafe conditions due to lack of accommodations by UPS;
3. UPS also lacked a system to alert these employees as to emergencies, such as fires or chemical spills, to ensure that they would safely evacuate their facility; and
4. UPS had no policy to ensure that deaf applicants and employees actually received effective communication in the workplace.

The outcome was that UPS agreed to pay a $5.8 million award and agreed to a comprehensive accommodations program that was implemented in their facilities throughout the country.
