I don’t have to prove personal experiences or feelings when they have nothing to do with declaring fact.
Did I ask you to prove you’re a pizza delivery boy, did I ask you to prove you hit women, did I ask you to prove your sister is a whore? No, because proof of those things does not add to the conversation, and there is no established history of fact for them.
Will I ask and expect you to prove that bones do not have nerves, that averages are not exact numbers, that supply and demand do not affect gas prices, that nominal pricing is the only relevant price, that history has nothing to do with judging something, etc.?
Yes I will. All of those claims fly in the face of well known and proved information and facts.
