It's acceptance in society teach people like you to fear only those who murder the body while not fearing those who kill the soul. Compare Matthew 10:28. You show yourself one step closer to hell by defending evil and sin.
I think you are jumping to conclusions if you think the OP is
defending evil, it reads to me like he is trying to understand why the traditional teaching against ɧoɱosɛҳųαƖs is so severe as compared to the modern day position which is so understanding of their "alternate lifestyle choice". OP needs to understand that
marriage is quite different from a secular contract between two people which is all the government considers a marriage to be.
That's also why governments think they have the authority to dissolve the "contract" between 2 people (aka divorce). And if that was all a true marriage was, a legal contract between 2 people, then it would not matter who those 2 people were, or 3 or 4 or 10 or 20.
Perhaps the OP will spend some time reading on what true
marriage is all about.
