Here ^ you are, pathetically pretending, to the deception of exactly nobody, that allegations and accusations cannot stand as evidence (i.e., are to be dismissed out of hand) – as if there were no reason to even consider evaluating the credibility of the source (in the present case, unlike with Thernovich and Breitbart and Gatewaypundit and all the other benthic shitholes you’ve been drawing from for a year, the sources are the CIA case officers involved in the investigation via a war correspondent of stellar credential and reputation) and/or the extent to which the allegation accords with the other relevant evidence (fantastically).
…But here you were, back before you needed to adopt the above transparent and idiotic pose in order to avoid yet another public faceplant into the cold concrete of your inability to form and defend coherent thoughts in the English language:
Do you see what this is? It’s you losing, definitively. Because it turns out that you do believe allegations to be legitimate forms of evidence, and you believe them to be so to an extent that is commensurate with the strength of their sourcing and the degree of correspondence between them and the other relevant facts. You’re so fucking pitiably easy to beat that it isn’t even fun.
Also, if you don’t actually know the answer to your third question, why are you pretending to have an opinion on any of this in the first place?
