Sexual orientation is a choice. Homosexuality can be classified as a form or mental illness. Therapy can successfully alter one's sexual orientation when there is sincere effort. Gay men have more of a tendency than heterosexual men to sexually molest children. Children raised by homosexual and by heterosexual parents will show developmental differences.
Biological factors determine sexual orientation.
Homosexual males are a real threat to heterosexual males. Public policy prohibits discrimination against homosexuals. Most stereotypes about lesbians and gays are, to a large extent, accurate representations.
