You’re a fool.
Luke Skywalker is a man. He’s a jedi. He grew up on a farm. He’s a hero to the rebellion. He’s the son of Darth Vader. These are all true statements everyone can agree on. Everyone knows all these things. It doesn’t matter that he isn’t real.
If you told me that Luke Skywalker was a tree, I’d call you a fool. Luke Skywalker isn’t real, but we can all still agree he isn’t a tree.
Hopefully, this example has hammered into your overly literal mind that facts can still be true and false when they describe something that doesn’t exist.
Atheists claim that Deus burns people in a lake of father, AND that he doesn’t exist. You still claim a version of him, just like you claim a version of Luke Skywalker.
Christians are calling you out for claiming that a fake version of Deus doesn’t exist. And they’re right, you’re fools for it. Deny the existence of the actual nonexistent christian god, not a fake nonexistent christian god.
