The point is whether you have the consent that you are brainwashed. The lies the huge difference. You don't seem to have the consent that you can be brainwashed by receiving secular education since childhood.
That's rather the question directed to yourself. Do you have the evidence whether Nanjing massacre ever happened. Or can you deny its occurrence due to the lack of evidence.
You are the one who's making straw man by asking for evidence of an historical event like Nanjing massacre.
That's an incorrect description of what Christianity dogmas are. To put it another way, if hellfire is a truth (for the sake of argument), how will you be able to convey this truth?
It's your another fallacy to ask for burden of proof. Do the police need to present you with proof in the case of an evacuation? Humans (perhaps except for you) don't ask for evidence under that "you make your run or you die" circumstance. Similarly Christianity is about such a message conveyed more than 2000 years ago. You either believe to make your run or you not. No one has the burden of proof to show you any evidence. In the end, it's your own life.
Burden of proof is only valid under the circumstance the you can stand neutral in a situation, but not in one which you either make your run or risk your own dead or alive.
Moreover, in terms of an advocate about a future event, it's joke itself to ask for evidence as no humans can reach a future event to gather evidence. You are fooling yourself by using such a straw man argument.
