Homosexuality has negative effects on the practicing individual and society. Compared to the general population, homosexuals are at an elevated risk for a variety of adverse health and mental health outcomes. The Gay Lesbian Medical Association (GLMA) describes the following detrimental effects associated with same-sex sexual practice: higher rates of HIV/AIDS, substance abuse, depression/anxiety, hepatitis, sexually transmitted illnesses (anal papilloma/HPV, gonorrhea, syphilis, and chlamydia), certain cancers, alcohol abuse, tobacco use, eating disorders and (in subsets) obesity.
A healthcare professional would never consider telling their patients who struggle with alcoholism or obesity (in spite of the fact that there may be genetic predisposition to these conditions) that they should celebrate their condition as part of the wonders of diversity. Such an attitude would deny their patients the treatment to allow them to avoid unhealthy consequences of those conditions. Why, then, should healthcare professionals condone homosexual behavior with unhealthy consequences as great or worse than alcoholism, when, in fact, treatment for homosexuality has a cure rate at least as good, if not better, than that for alcoholism?
