GG may be strident, but he generally backs up his points. He has a really good truth/falsehood ratio. The government and its apologists lie so much they can't tell the difference any more. Some apologists may just be misguided because everything from toilet paper receipts and up are highly classified now. and a 20M budget means nothing; how much is hidden in black ops or Department of Energy? The government, including the current administration, has been pumping propaganda and just pure bullshit for so long it's hard to guess when they might be telling the truth. GG has been a straight shooter with an excellent accuracy record, even if he is a pain in the ass at times.
It comes down to this: Do you want to believe an known blatant serial liar or an obnoxious generally truthful gadfly? Your choice.
You can easily guess what mine is.
