Theists, are you immune to being decieved?

Atheism is completely false if ANY deity exists.
Every single version of theism must be disproven.
Better get cracking. You got a lot of work ahead of you.

Every single version of theism, except for one, is false if any is proven true.

How does that follow? Can you see the people feeling different parts of the same elephant meme?
I am making an argument based on multiple types of theism being partly true not entirely true.

...A Christian is wrong unless the God of their bible is proven to exist and if the Jesus story is actually true.

NO! At best you could argue that the Christian might be partly wrong, if their understanding of one version of God - the one they mistakenly hold to - is unmistakenly proven to be something objectively different to the universally agreed concept of what the bible says.

You of all people know that biblical theists, while agreeing on much/most of the theological distinctives and yet can still disagree on various points. (Courtier's Reply)

Demanding unanimity as a benchmark is a bit too cute considering the category is atheism versus theism, not atheism versus catholicism or atheism versus protestantism.

...By your logic, you have to accept every competing theist claim since you have disproven none of those.

Nope. Even if I WAS mistaken, my view would still be partly entailed in theism more broadly.

If the polytheist one day discovers that what they previously thought was multiple different entities, was in fact different manifestations of the same single Being,
just mistakenly interpreted, you could hardly say they are 100% wrong about the existence of God(s).

Being mistaken about the nature of God is not the same as being mistaken about the existence of God.

...That means you have to accept that Islam is equally true to Christianity according to your own rules. Do you?

Islam is equally true to Judaism and Christianity on a huge number of matters. Ten of which I can name off by heart.
