describe a point in american culture where incest is fully accepted and legalized in all,levels

As of my last knowledge update in October 2023, there is no point in American culture where incest is fully accepted and legalized at all levels. Incest, defined as sexual relationships between closely related individuals, is generally considered taboo and is illegal in most states across the United States. While there may be subcultures or individuals who have unconventional beliefs regarding incest, these views do not reflect mainstream American culture or legal standards. Legal frameworks in the U.S. are built upon historical, social, and moral considerations that typically reject incest due to potential issues related to consent, genetics, and societal norms.
