How do you figure that adultery is conservative? Do you also consider pedophiles ‘christian’ if they go to church on Sunday?
A thing is or it is not. When you act in ways counter to the thing, you arent that.
I don’t figure adultery is “conservative”.
Nevertheless, your statement is a logical fallacy, partly because very little in human behavior is 100% consistent.
"Conservative" in the U.S. is a political and legal worldview involving constitutional principals, and protecting rights. It is not some moralistic lifestyle choice. You don't get to just make up definitions.
