Shouting and bullying and badgering, sure signs of an agitprop or an needy ego.
Well he's also posted images of bottles filled with what he claims are samples removed from the bodies of corpses he embalmed.
If the guy is real, and he has real samples, then it's more than just a claim.
It may be a hoax, but I can't tell if that is true just yet. It sounds plausible to me.
