If gay marriage between consenting adults is ok, why isn't incestual marriage also ok?

Obviously the incest question has been used as a "gotcha" against gay marriage, when it is often an intellectually weak argument and not thought through, but I wanted to take a little time and develop the analogy and see if we can get to a spot where proponents have to rely on a "it's just ok, and that isn't"

So much of what frustrates me is the reverse engineering of morality based upon a personal anecdote which is unilaterally held as "ok". For example, I'm not going to name names, but there are some Catholics whose opinion on LGBTQ issues is flavored by an LGBTQ loved one. Rather than saying "based on my moral beliefs, or the set of moral beliefs I claim to adhere to, is my loved one living morally?" it is "There's no way my loved one can be doing anything bad, so they must be ok, and the teaching is wrong or needs to be nuanced".

So in my extremely gerrymandered scenario: a son who was given up for adoption meets his biological father for the first time at the age of 25. They fall madly in love, romantic "husband and wife" love. Stripped of any familial power dynamics, worries about malformed offspring, grooming or what have you, why is a standard run of the mill gay marriage/homosexual relationship ok, and this particular incestual relationship not?

For those that say this a very unlikely scenario which is used to paint all of the other vast vast majority of gay relationships in the same light, I bring up the abortion scenario. For so long we've heard the sad tale about the 14 year old girl who is raped by her father and is forced to bear his child in a pregnancy that will possibly kill or maim her, when that's a ridiculously contrived scenario used to gloss over the fact that 98% or so of abortions are done out of convenience.

For those that argue that 2% is still a hell of a lot more than whatever the prevalence of the scenario I describe is, I don't disagree, but that's still not addressing the morality of the question.

The love is love tautology always leads to, if not gnosticism, then heresy that's at least Gnostic adjacent. Because it subordinates our bodies to our appetites. If what our organs do isn't revealing in the slightest on questions about sexual morality, then can we really intuit anything at all about God from His design? It calls into question the whole pretext given for our ability to reason and to make inferences about God through any means other than divine revelation. Are we even made imago Dei if God's design is that baffling? How do we know it's bad if I eat a dozen hot donuts for breakfast every morning absent divine revelation, if we're not our bodies? I genuinely love donuts so much, and the fact that my body is not designed to run on donuts is not an indication that it's harmful or that I relate to donuts in an unhealthy way.

And through that lens at least, it's MORE difficult to intuit a problem with incest than gay conjugal relationships. So yeah, I don't think it should be treated as some kind of gotcha. It's a very good question. Why this and not that?

I would be interested to know why this is such a passionate topic for you?

Do you perceive homosexuality to be a greater sin than others?

Is it worse than murder, theft or adultery.

I honestly don't know that it is and I say its no worse than lying.

Both are worthy of death.

As a married man I would find adultery a far worse sin as you have failed a sacrament.

Growing up Protestant being Gay was the worst thing you can be. As an Orthodox person I don't have the same perspective.

Just to jump ahead I don't have any gay family members and I am not gay myself so its not a stance based morality of mine.

It's not the sin of homosexual activity itself rather than how it's being used right now. It's the social issue dujour being used by Big Demon to try and confuse the faithful and splinter the church even further.

It's the issue causing the German church to once again flirt with outright heresy that ends up in schism, it may seem like a tempest in a teapot, but the white washing of homosexuality attacks the human person and our design at its very core. Where adultery and fornication are sins against temperance and chastity, which can be rightly ordered through discipline; homosexuality attacks the nature of man and the economy of the trinity.

So in short, homosexuality is the Trojan horse being used as a vehicle to attack the very foundation of the Church.
