Maybe he's talking about the "conspiracy" of vaccines, but he's too lazy to actually look up the overwhelming evidence. Maybe he's trying to say it's a vast "conspiracy" that Monsanto is causing the obesity problem in this country, with their tinkering with the DNA of things, placing bacteria into the seeds so that they kill the bugs, but consequently, also make the person consuming it fat. Cancer rates are soaring, and it just can't be that they're tinkering with the things that God made and that the western world consumes daily, and is the only constant link. But meh, that's just conspiracy.
I think people that believe that we're "vast conspiracy theorist" should return to "fish kill" where they belong. Like the old saying goes...
