I believe that if they can't refute your rock-solid presentation of Scripture, then they will probably try to belittle you, minimize you, smear you, or say anything else that will cast doubt on the things you're showing in the Bible. They'll believe their own lies and that will be the excuse they need to keep their idol because they will believe you are a heretic so you can't possibly be right in their mind. Also, they probably hope that in some way it will deter others from believing you and, ideally, wear you out until you're tired of being here.
That is what I suppose, but good luck getting any of them to admit that's what they are doing, let alone say amen to any verses you quote. You're showing a lot of things the Bible says that hurts their eyes and ears. It becomes a matter of their religion against Scripture and their effort to justify themselves by whatever means possible at some point. Just be glad they have been stripped of their claws and fangs in the present day. I hear the Trinitarians were a blood thirsty group throughout most of their history. Fortunately, we can openly disagree with them nowadays without getting martyred.
