You can’t brush these conspiracy guys off by calling them wack jobs. You need to use their own (what I call) “handicapped logic” against them.

Yoshi, if all these big Phramas have the answers to cancer and they are all keeping the secrets to themselves for their own personal greed. Then wouldn’t it take just one of them to be, I don’t know “GREEDY” and monopolize the cure against the competition. They would dominate the world if the had patents on the cure.

But NO, all those massive evil greedy corporations are all playing nicely together, holding hands and not one individual would ever think of taking it all for themselves and destroying the competition and writing themselves into the history books.

Done,

Sirs I present to you “Handicapped logic”
