“Gage is just a promoter …”
Yes, Gage promotes and coordinates the evidence for all aspects of the theory that the Twin Towers were explosively demolished, a theory that you say is unscientific. However Chandler is only responsible for a small part of that evidence. Furthermore, Gage is much better known than Chandler.
If your reasoning is that a 9/11 conspiracy theorist is responsible for the damage to 5G masts in Birmingham because the arsonists there have been encouraged by his bad grasp of science then surely Gage has been far more influential than Chandler and must shoulder the lion’s share of the blame?
I’d like to get this point clear before we tackle the question of whether Kennedy assassination conspiracy theorists also share some of the blame.
