This is literally the same strategy used by the west in the "anti Stalin paradigm" which is a term coined by Grover Furr. In his many years of research into the Soviet Unions and western propaganda he states that basically the west can make up anything they want, any accusation at all, and if you question it in any way you are now a sympathizer with the accused and their made up crimes. So if I said Stalin personally strangled 100 children for no reason, and you ask me for a source, the reaction would be me accusing you of approving of Stalins strangling of 1000 children.

As we see, this is a tactic they employ against any target they wish.
