About homosexuality

When we assume that the main purpose of a human is to reproduce, then the optimal sexual orientation for a man is to perceive women as attractive and for a woman to perceive men as attractive. This optimal orientation avoids individuals wasting energy in sexual efforts towards a partner of same sex, which would be useless. Accordingly, we should repress and consider insane any human with a non-optimal orientation.

But things get more complex when we realize that the meaning of life is more than having children and that increasing our population (the number of individual humans living on earth) is not a primary concern of our species.

I suggest the following definitions.


The (normal) sexual orientation of a human feeling sexually attracted by other humans of the opposite sex.


The sexual orientation of a human feeling sexually attracted by other humans of same sex.


The sexual orientation of a human feeling sexually attracted by other humans of both sexes.


An general word for humans with an extraordinary sexual orientation or identity, i.e. who don’t classify as heterosexual and cisgender.

Originally meaning “strange” or “peculiar”, queer came to be used pejoratively against those with same-sex desires or relationships in the late 19th century. Beginning in the late 1980s, queer activists began to reclaim the word as a deliberately provocative and politically radical alternative to the more assimilationist branches of the LGBT community.

sexual orientation

An enduring pattern of emotional, romantic and sexual attractions developed as the result of a complex interplay of genetic, hormonal, and environmental influences.

sexual identity

How one thinks of oneself in terms of to whom one is sexually attracted.


The fact of having a sexual identity that differs from your birth sex.


The fact of having a sexual identity that matches your birth sex.

birth sex

The sex that has been assigned to you when you were born.


A range of negative attitudes and feelings like contempt, aversion, hatred or antipathy toward humans who are identified or perceived as being homosexual.

It is often expanded to otherwise queer people (bisexual and transgender).

While homosexuality is a deviation from norm, it is not itself a source of negative psychological or social effects. There is no valid reason to feel guilty about being homosexual, and there is no valid reason to reject homosexual humans from society. Homosexuality is an exciting phenomena at social, ethic and scientific level and an enrichment for humanity.

Homosexual humans are not disabled. They can marry and unite with a human of opposite sex and have biological children.

There are cases where homosexual orientation could successfully be changed at least partly into a heterosexual orientation.

Homosexual humans sometimes refrain from openly identifying as such due to homophobia, which causes stigmatization and discrimination.

Homophobia is based on ignorance, irrational fear and obsolete religious beliefs.

Homosexual behavior has also been documented and can be observed in non-human animal species.

Transgender people

Note that transgender is fundamentally different from homosexuality. For transgender people it is the sexual identity, not the orientation which is extraordinary.

Transgender people experience a sexual identity that is inconsistent with their biological sex. This is either a man who would prefer to be a woman, or a woman who would prefer to be a man.

A transgender individual who desires to permanently transition to the gender with which they identify, usually seeking medical assistance including hormone replacement therapy and other sex reassignment therapies, may later in their life suffer from side effects which might be more problematic than the original problem.

Sexual disorders are neither sin nor normal

In 2017 there were still humans of moral authority who publicly declared that homosexuality is a sin. In 2017 there were still humans who seriously considered suicide as the only solution for their sexual identity or orientation diverging from the norm.

On the other hand, the biological sex of an individual have deep influences on its life and cannot be changed at will without potentially causing serious other problems.

LGTBQ and God

“In cultures influenced by Abrahamic religions, the law and the church established sodomy as a transgression against divine law or a crime against nature. The condemnation of anal sex between males, however, predates Christian belief. It was frequent in ancient Greece; “unnatural” can be traced back to Plato.” (Wikipedia)

Many leaders of Jewish religion and its derivatives, Christianity and Islam, still stigmatize homosexuality as something bad. I think that it is time to review some values.

Let’s acknowledge that, until some generations ago, humanity had no scientific understanding of what homosexuality is. Let’s acknowledge that in ancient times, people were afraid of this phenomenon. And let’s acknowledge that some parts of our Holy Scriptures reflect that fear.

But let’s get realistic. Human science has explained homosexuality well enough. It can’t be against the will of God. We cannot call it a disease. Not even a disorder. It is not more particular than being a twin or having read hair. Let’s get rid of ancient opinions that have become obsolete.

Cultures don’t change quickly. Christian churches have learned already. Homosexuality itself is no longer a sin for Christians. I believe that it won’t take very long –only a few generations– until LGTB people will get fully acknowledged by all Christian churches.
