First, I flippantly refer to the LGBT community as the Alphabet People, or the Rainbow People. I choose to mock that which I believe is ridiculous.
Second, it’s important to understand that the LGBT community, like Black Lives Matter, is an interest group. It’s an organization, receiving funding and donations to further changes to public policy. Just about everyone equates the interest group with all gay, lesbian, bi and trans people, which is wrong in more than one way. We shouldn’t assume that people with similar characteristics have similar beliefs, as this erases their individuality.
Third, there’s a whole lot of things to discuss, that people aren’t aware of. I’m going to speak of both the interest group and Gay, Lesbian Trans, Etc.
Homosexuality used to be viewed as a mental illness. Though we claim that we don’t like to stigmatize mental illness, it’s still considered offensive to assert that homosexuals are mentally ill.
This was largely due to an emotional appeal by Dr. Henry Anonymous (Dr. John E Fryer) at an APA conference. The central argument was that having homosexuality considered as a mental illness, this allowed society to ostracize them, and allowed for open abuse and discrimination against gays.
It should be noted that oppression due to illness should never justify changing the scientific view that it is an illness. Lepers were cast out of cities to live in camps and ostracized by society, but it would be ridiculous to use this as a justification to suggest leprosy was not an illness.
Theories of homosexuality fall into one of three categories:
(that it is a mental illness)
To find how much genetic vs environmental influence there is on a mental illness, researchers use genetic twin studies. If a condition were entirely biological and genetic twins have the same DNA, it would be expected that both twins would either have it, or not. For homosexuality, the genetic influence is about half, the other half is therefore environmental. Mental illnesses come with other, predictable mental illnesses (comorbidities) and must have an etiology, and this is true for homosexuality, lending to the theory that it is psychopathology.
(that it is a phase one may grow into and out of)
This is best exemplified by the relatively common experience for young, teenage boys to have one or two homoerotic wet dreams. During adolescence, it is relatively common to have peculiar fantasies, which come and go. Should one be fixated upon for longer than six months, it becomes a sexual fetish (paraphilia). This may also be true for homosexuality. The first three Diagnostic Statistical Manuals counted homosexuality as a paraphilia. My own theory regarding immaturity involves teenage boys who have a homoerotic wet dream, and are distressed by it. As a result, they question their sexuality and overcompensate, lashing out at anything that reminds them of this uncomfortable self-doubt, regularly condemning benign interactions as “that’s gay”. They also lash out at homosexuals and verbally or physically attack them, as a way of reassuring themselves that they are heterosexual, attacking these people as an effigy of themselves and reasserting their masculinity. This is my own personal theory of homophobia.
(that it is natural, similar to left-handedness)This category regards homosexuality as something you’re born into. There’s been a big push in our culture to “normalize” homosexuality, with the expectation that once destigmatized, more people would admit they are gay, and it was expected that they would make up 10-15% of the general population, falling within 2 standard deviations of the mean, within the normal curve. This means it would literally be normal. That has yet to happen. All over the world, studies show only 1-4% of the general population is gay, which means it does not fall within the normal curve and thus is abnormal by definition. Since normal variance also presupposes one is gay from birth, the two biggest justifications for this theory don’t appear to be true.
