What is the term for fear of and prejudice against homosexuality?

The term that describes fear of and prejudice against homosexuality is homophobia. Homophobia encompasses a range of negative attitudes and feelings towards LGBTQ+ individuals, particularly those who identify as gay or lesbian. This term illustrates social stigma, discrimination, and hostility directed toward individuals due to their sexual orientation.

In contrast, transphobia refers specifically to negative attitudes towards transgender individuals. Sectarianism typically relates to divisions between different religious groups rather than sexual orientation, while sexism involves discrimination based on gender, which can intersect with issues of sexual orientation but does not specifically address attitudes towards homosexuality. Therefore, homophobia is the most precise term in this context, as it directly pertains to the prejudice against and fear of homosexuality.
