Yes. This thread has been specific to Silverstein. As far as I know, Sizzler has not yet put forth any complete conspiracy theory, so there is no reason yet to connect the specific arguments he's made in this thread to a 'conspiracy that the truther's claim'. When Sizzler does put forth a full theory, if it includes Silverstein as a co-conspirator, then you can claim that he has implicated him in a murder, and depending upon the quality of the argument, you can decide if the implications are baseless.
(So far, they promise to be pretty baseless Sizzler

)
