I find it a little difficult to figure out the main point or question you are trying to get across, but I will try to respond the best I can and you may clarify your point or question if you think necessary.
First, I think the behavior of a rapist is sinful whoever they are or whatever relationship they are in because their behavior is using and defrauding another person for their own self-centered reasons.
Secondly, I think there is more to marriage than love, friendship, family, job, house, children, etc. Previously, I have posted that I believe the scriptures reveal that God created man in His image. Man meaning, not man alone or not female alone, but male and female represent the image of God. So a marriage between a male and female is a picture of God's image. In the NT it is also shown that marriage between a man and woman is a picture of the relationship between Christ and the church, His bride. This representation does not occur, nor is the wholeness of God's image displayed in a male/ male or female/ female union. According to the scriptures since sexual relations unite two as one they are reserved for the marriage between a male and female because it is this unity of male and female qualities which display God's image, whether in Christian or non-Christian marriages because God designed marriage as such, between male and female.

I just find holy matrimony does not depend on one one way of consummating ones love in a non-lustful way. In the Catholic Church, intercourse is preserved for procreation. Based on their logic, then yes, homosexuals cannot marry because the Church doesnt recognize consummation behind which parts fit where. As long as it is a healthy and natual consummation between two people regardless the gender I see no issue with it.
Its not rape.. Its not abuse. Its not prostitution Its not idolotry,
Its not in the Bible. If the Bible said "two people of the same gender cannot inter into holy matrimony
because they do not have the ability to love each other as heterosexuals do, although I disagree, it is logical.
What the Bible says is that homoosexual (as per authors translation) acts (not people) are not to be practiced because they are alike to rape,, abuse, idolotry,etc. NOT love, consummation, and holy matrimony.
God is refering to a totally different context and intent of two or more people having sex out of lust. These people could be straight, bi, trans, gay, or lesbian. God doesnt differientate between these titles of ones sexual orientation and identity.
Take someone who is transgender. The Church denies this male marriage because of how he identifies himself as a female. To
her not him, she is straight. To the outside, he is gay. In reality, he is not.
God does not mention this in the bible. Most likely it was never an issue until whomever struggled through it went against the cultural practices at that time. In Muslim countries, they may very well be lesbians of course but to go outside their religious and cultural practices is higher concern than how one identifies oneself (unless sommeone corrects me) Thats the same in african american culture and that I know for a fact. In many African American (I hate to say it that way) communities, the core of their community is Christ. Yet, depending on the area (really, depending) is how one accepts a person compared to another area.
Anyway, my point is context not content.
The way god is potrayed sounds like he is zues on star trek or something telling people to bow down to him and if they dont do X they will be punished. If god is that way, I just cant see it in reality. I cant see how life not a being or entity, but life can descriminate. We label life. Not the other way around.
