what do psycologists say about homosexuals?

Answer 1

The question is unclear. Did you mean:

In psychology, what are the different theories relating to homosexuality?

If so, I suspect there is a wide range of theories and point of views in psychology regarding homosexuals. Homosexuality and Psychology have an intertwined history in that Psychology gave the sexual preference its final classification declaring

homosexuality: a separate sexual orientation and a deviant sexual practice.

From the nineteen century up to the 70’s, psychology considered homosexuality to be a psychological disorder, and homosexuals as individuals who must be “forcibly cured.” Most psychologists concluded that homosexuality was a curable condition.. Freud’s psychoanalysis was frequently used in the treatment of homosexuality. Psychology’ point of view on homosexuality participated to an increasing number of homosexuals placed in mental hospitals and prisons. A variety of therapies to "cure" homosexuality, included aversion therapy, nausea producing drugs, castration, electric shock, brain surgery, breast amputations, and hypnosis…

In the 70’s, the APA finally removed homosexuality from the sexual deviancy section. Not sooner than 1992, world health organization ceased to classify it as a mental disorder. The reasons for the change are still being debated by theorists and else.

Nowadays, the majority of mental health professionals renounced the idea of homosexuality as a mental disorder. Although few conservative and religious groups still advocate an alternative psychology and regards homosexuality as a sexual disorder.
New psychological theories focus now on heterosexism and hatred of homosexuals (or homophobia).
