MacGregor says do not believe anything that comes out of the FBI's mouth
Who?
The fighter? LOL.
Go to Wikipedia and look for Argument from Authority, aka Appeal to Authority, aka
argumentum ad verecundiam.
If a qualified expert in a given field -- say, an astrophysicist named Dave -- tells us "Comet Asshole is going to hit Earth in 2035," that's cool. I'll hear him out, though I would seek out other astrophysicists' take on Comet Asshole.
Citing Dave as a source isn't illogical. He IS an expert insofar as comets potentially fucking us up are concerned.
If I understand who you mean by MacGregor, it sounds like he's taken too many shots to the head and, as a result, I don't believe him.
(Hint, Doug: I didn't fully mean that last bit. Even IF the dude was punchy, to say he's wrong on that basis is another fallacy -- specifically, the Ad Hominem. Even drunks, morons, and broken clocks can tell the right time on occasion

.)
I object because, while I fully agree to not blindly accept anything from my government prima facie, I don't accept the premise that the U.S, government, or its FBI, is purely spewing bullshit on the basis of MaCGregor's claim.
He can do better...
He also.said the deep state are the elections and shitsa is in no way a democracy
Watch the vid I posted
I don't care what he said. Where are his qualifications on the matter?
Barring that, where are his arguments?
I can shout slogans off rooftops all day, but sans the wherewithal to back those up, I am an idiot. As Shakespeare said:
Life's but a walking shadow. That struts and frets his hour upon the stage. And then nothing is heard no more. It is a rale told by an Idiot, full of sound and fury. Signifying nothing.
