The test of a false god. Most theist will agree there are "false" gods. So I came up with this to help determine what a false god is.
If a god does not exist the followers must have faith to believe in it.
This part is easily accepted. Them I mention that there is no god thst does not require faith.
So far every theist has been stumped and has not even tried to respond. It is important to be nice when pointing this out. At this point I simply say that that is why I do not believe.
What statements have worked forr you?
From my experience believers will generally say something like, "Yes, but MY God is real." So, being stumped, as you put it, doesn't prevent them from embracing logical absurdity and contradiction. Since religion is always based on bad history/mythology, unproven supernatural claims, and fear, I have not found logic a very effective tool in engaging with believers. But, I admire your determination to try.
I agree with you. The more religious they are the less they care about anything but what they want to believe.
True theists are an endangered species in the UK so I rarely meet one. But that is a really good tactic.
You live in a country with an official religion that is not religious. I live in a "secular" country that is bat shit crazy religious. I can say that I was one of them.
