The veracity of a hoax can only be maintained via the public humiliation of the non believers by the members of the cult.......
We’re seeing that right here every day.
(First lets understand that a hoax cant have veracity.)
Second, to analyze the veracity of Q you need to eliminate defeaters.
Very similar to analyzing the theory whether Obama/Clinton were trying to destroy our country, or whether they routinely committed murder. For example, if they followed a moral code preventing such behavior, that would be a defeater for the theory. As we know, such defeater is not present.
With Q, you have to ask yourself is there any reason to think Trump wouldnt invent such a thing, then weigh it against reasons to think he would.
