I have only your words. Why do they seem to be so easily ‘misunderstood’ as you claim?
It does not matter how the homosexuals see it. The behavior is wrong. The activity is wrong. Homosexuality is not an identity, it is a behavior.
We are given these ‘needs’ you refer to. They are for procreation and couple-bonding, AND these needs are to be fulfilled within the bounds of marriage. And marriage is the institution God created that is the union of a (as in one or a single) man and a (Again, just one) woman.
Other desires, and their activities, are so far beyond wrong they were given a special word to describe them - abomination.
Seems simple and clear cut to me, regardless of how a homosexual or lesbian, or zoophile, or pedophile, or necrophile might perceive it.
I’m happy for you to have things appear so simple to you.
