From the Family Research Council:
Myth No. 1: People are born gay.
FACT: The research does not show that anyone is “born gay,” and suggests instead that homosexuality results from a complex mix of developmental factors.
Myth No. 2: Sexual orientation can never change.
FACT: Thousands of men and women have testified to experiencing a change in their sexual orientation from homosexual to heterosexual. Research confirms that such change does occur—sometimes spontaneously, and sometimes as a result of therapeutic interventions.
Myth No. 3: Efforts to change someone’s sexual orientation from homosexual to heterosexual are harmful and unethical.
FACT: There is no scientific evidence that change efforts create greater harm than the homosexual lifestyle itself. The real ethical violation is when clients are denied the opportunity to set their own goals for therapy.
Myth No. 4: Ten percent of the population is gay.
FACT: Less than three percent of American adults identify themselves as homosexual or bisexual.
Myth No. 5: Homosexuals do not experience a higher level of psychological disorders than heterosexuals.
FACT: Homosexuals experience considerably higher levels of mental illness and substance abuse than heterosexuals. A detailed review of the research has shown that “no other group of comparable size in society experiences such intense and widespread pathology.”
Myth No. 6: Homosexual conduct is not harmful to one’s physical health.
FACT: Both because of high-risk behavior patterns, such as sexual promiscuity, and because of the harm to the body from specific sexual acts, homosexuals are at greater risk than heterosexuals for sexually transmitted diseases and other forms of illness and injury.
Myth No. 7: Children raised by homosexuals are no different from children raised by heterosexuals, nor do they suffer harm.
FACT: An overwhelming body of social science research shows that children do best when raised by their own biological mother and father who are committed to one another in a lifelong marriage. Research specifically on children of homosexuals has major methodological problems, but does show specific differences.
Myth No. 8: Homosexuals are no more likely to molest children than heterosexuals.
FACT: The percentage of child sexual abuse cases in which men molest boys is many times higher than the percentage of adult males who are homosexual, and most men who molest boys self-identify as homosexual or bisexual.
Myth No. 9: Homosexuals are seriously disadvantaged by discrimination.
FACT: Research shows that homosexuals actually have significantly higher levels of educational attainment than the general public, while the findings on homosexual incomes are, at worst, mixed.
Myth No. 10: Homosexual relationships are just the same as heterosexual ones, except for the gender of the partners.
FACT: Homosexuals are less likely to enter into a committed relationship, less likely to be sexually faithful to a partner, even if they have one, and are less likely to remain committed for a lifetime, than are heterosexuals. They also experience higher rates of domestic violence than heterosexual married couples.
