The laptop story was obviously real, the QAnon part was just randos making wild conjectures and blowing it up into completely unrelated territories like population mind control, new lizard world order, child blood drinking, and similar nonsense. I suppose, when I look at it from the other side, when the emphasis is placed on the easily discreditable parts of it, then that makes it look like the entire story is fake. Perhaps the biolabs really are producing WMDs, it just so happens that this one guy presented the story without evidence it and it turned into this entire thing before actual evidence of anything was discovered.
