Homosexuality is entirely normal. Normalcy can be defined statistically—as what's common in a population—and socially—as what is accepted by society. Though less common statistically, homosexuality's minority status doesn't make it a disorder, sin, or crime. For example, geniuses with extraordinarily high IQs are also statistical outliers but are not marginalized in the same way.

Sexual activity traditionally fulfills two roles: reproduction (species continuation) and pleasure (bonding between partners). Though homosexual relationships don't result in biological children, many heterosexual couples also forgo parenting, and many homosexual couples choose adoption. Consequently, homosexuality is neither immoral nor illegal and should not be viewed as a deviation. It is a natural facet of human diversity, not merely a personal choice.

Homosexuality is neither new nor problematic, but a consistent aspect of human history. Archaeological findings confirm same-sex attraction existed in prehistoric cultures. However, despite its historical presence, the issue has been deeply controversial in fields like medicine, law, and social policy. Homosexuality was classified as a psychiatric disorder in the DSM until 1973 and remained in the ICD until 1991.

Although progress has been made in decriminalizing same-sex relationships, stigma and discrimination persist in many parts of the world. LGB individuals continue to face discrimination, including verbal and physical abuse, social exclusion, and legal penalties in various countries. The ongoing criminalization and marginalization of sexual and gender minorities contribute to their societal challenges.
