Final answer:
The claim that homosexuality is universally considered the norm and is completely accepted in the United States is false. Although acceptance has grown, the U.S. is still a heteronormative society facing challenges in complete LGBTQ inclusion.
Step-by-step explanation:
The statement that homosexuality is considered the norm in the United States and is completely accepted is false. While there has been significant progress in the awareness and acceptance of different sexual orientations and identities, the United States is still predominantly a heteronormative society, where heterosexual orientation is often considered the default. The influence of a heteronormative society can result in the treatment of LGBTQ people as 'others,' leading to social exclusion and discrimination. Furthermore, historical contexts show that laws against homosexuality have been present, and there has been opposition and discrimination in various social institutions.
Despite the legalization of same-sex marriage nationwide in 2015 and the active LGBTQIA+ movement calling for acceptance and legal recognition, it's clear that homosexuality is not universally or completely accepted as the norm within the U.S. The notion of heteronormativity suggests that much of society still assumes heterosexuality as the standard orientation, which continues to marginalize homosexual relationships in certain aspects of social and private life.
