Avoid identifying gay people as "homosexuals" - an outdated term considered derogatory and offensive to many lesbian and gay people. The term - “homosexual” is considered stigmatizing (particularly as a noun) due to its history as a category of mental illness, and is discouraged for common use (use gay or lesbian instead). Until 1973 “Homosexuality” was classifed as a mental disorder in the DSM Diagnostic and Statistical Manual of Mental Disorders. This is just one of the reasons that there are such heavy negative and clinical connotations with this term.
