The first and most blatant reason,
Is that it is dirty. Butts and mouths are not
Orifices  for sex organs.
And all the other ways
Seem to be artificial
Or not so satisfying.

It is also a non reciprocal way
Of having sex. There is always
One receiving pleasure
And another not.
Meaning it can never be equally satisfying.

It is self centered.
Homoeroticism is a sign of narcissism.
It develops in the minds of those
Who are selfish. To desire one's
Homogenous sex, means one
Has a desire for their own form
And not the opposite form.
Meaning, their libido is turned inward
And when this happens it is classic narcissism.
You can tell by the voice acting men use
That they are being narcissistic;
And the women make themselves look like men.

It skews the Logos.
People who are homosexual
Cannot---I've never met one---
Know right from wrong on any
Basic level. Therefore, it creates 
A slippery slope where it slides
Into worse and worse behaviors.
Such as right now, with Pedophilia
Being attempted to be normalized
And men competing in women's sports.
People who are homosexual
And those who accept them
Cannot know what is good or right
In order to distinguish it from evil.

It also creates a strain on the supply
Of healthy sexual partners.
Those who are homosexual eat up
The surplus of mates, and therefore
Create scarcity for spouses within the culture.
This, in turn, spreads frustration
And increases the occurrence of Involuntary Celibacy.
Because spouses are harder to come by
When three out of every fifty people
Are cut from the gene pool.

And finally, it does not create life.
It, being purely hedonistic,
Encourages others to view sex
As a toy, and not a serious bodily function
Which can create a human life.
Thereby, Homosexuality leads
To an attitude about sex that it can be
Merely about pleasure.
And thereby, it causes those
Within the culture to view sex
Hedonistically. And thereby
It leads to unwanted babies,
And therefore abortions,
And therefore unloved children,
And therefore it destroys
The culture's fidelity.
As, when a culture's view on sex
Is skewed, it cannot be happy.

God why do You make a mockery of me, when I just tell the nations the truth? Why do You give me into their hands, and cause them to have their way, and cause my vision to fail? Do You love sin? Do You love oppression and violence? Why do You cause the sinner to rejoice, and the repentant to be in misery? Why do You cause trouble for the righteous, and give a smooth way to the wicked? Selah… I know… for there is no righteous judgment in the land, and sin is elevated, therefore the righteous suffer, and must so until Thou establish truth again. Why do the selfish and abominable get their meat, and those who have waited for You for decades find themselves about to be cast out in shame? Why do You let the dogs have love, and the patient saints, who would do good with Your gifts, why do You cause them to pine after Your commandments? Do You favor the wicked? Selah. No, it is that the judgment is nigh the land, and the thieves, liars, dogs and sorcerers shall be brought to an end. For while my drink is shortened, and my needs are not met, You plentifully give shelter to the wicked, and I ask why? Why do You show favor to the wicked? Why do lies get established, and why is the truth cast down? Why are strange things being done, and nobody tells the truth? And the one who tells the truth, You strike as if a false prophet, and all Your people mock? No, LORD, establish me, for I am Your Servant and have not lied. Yet You gave me over to the Accusers and mockers, and have not established me. Yet, You shall at the time appointed, return and establish judgment. For I am Your servant. And I shall perpetually worship You. For You are good, and I seek Your face so mercy shall be set aside for me, great and tall, and I shall drink of living waters, and eat the fruit of life.
