I'm not saying that you think everyone is lying to Harry. I'm saying that whenever someone provides something from the text that runs counter to whatever theory you're arguing for, your default response it "that isn't evidence that I'm wrong, it just proves that that character is lying/Harry is misinterpreting that/Jim is tricking us/whatever".
Which is especially ridiculous when the character in question (Kringle) is a Fae, and therefore physically incapable of lying.
Quite frankly it makes it near impossible to have any sort of reasonable discussion with you because you fit the evidence to your conclusion, rather then drawing a conclusion from the evidence.
