" It was the same sort of conspiracy theorist thinking that is happening nowadays."
To a degree yes, but of course the influence of the Masons in the areas you discuss was insidious and corrupt, and though the movement is waning, it still goes on today too.
The more outrageous Conspiracy theories of today are laughable of course, but the linking of say Russell or Rutherford to the Masons is not too unbelievable, and would be quite damning, but there is simply no solid, or even near satisfactory, evidence for it, or for any links by JW's today.
