Surely there were many people that Jesus encountered who were sleeping with women not their wives, and maybe even males. But the Bible does not record a single instance where Jesus put anybody to death.
And in the one case where we are explicitly told that he is dealing with a woman who had committed adultery, he stopped people from stoning her, and then sent her away.
I do believe that there are people here who, if they saw a man lying in the street bleeding out, and noticed they were gay, would actually let them die. But I don’t believe that is a necessary or even expected part of being a conservative.
People have value because God created them. And all have sinned, and if we used “sinner” as a reason to not provide services to people, we would never serve anybody anything.
Nobody said “sinner” by itself. The qualifier is repentant or unrepentant, and doing something deliberately for someone openly unrepentant makes one an “enabler”, to use modern parlance (take note of 2 John 1:11).
