Just the stuff the Heartland Institute does is enough to write a book about and still not a peep from the usual crowd.
The War-for-Oil conspiracy theories are proven correct.
The suppression of 'free energy' is discussed widely as being a result of oil-industry repression.
And on and on.
Because it hasn't. The "free energy" stuff is way off the mark and pales in comparison to absolute kookery of weather machines being responsible for things climate change is actually doing.
They don't have a solid grasp of reality and it shows in how they're unaware about the specific things the oil industry is doing. Much of their rhetoric is big oil propaganda being repeated anyway.
War for oil isn't a conspiracy - it's such obvious public knowledge that there are memes about it. Yes, the country that is a major oil producer and in the currency of which most if not all oil transactions are done uses its military might to preserve the status quo - that's hardly a secret.
Your disdain for the conspiracy theorist scene is mirrored in that scenes disdain for justice.
In the case where there is actionable justice that can be achieved, the conspiracy theory is no longer a theory - the conspiracy is prosecuted in the courts of our proud nations' democratic institutions.
