Found this thread and created an account to post here. I've been following Joshua for a while.
A few things to keep in mind:
Accounts
Joshua has created hundreds, possibly thousands of different YouTube accounts. If you don't believe me go to YouTube and type in "papaw duffman". Not only does he create new accounts (usually a fictional character or person he knows in real life that he is sort of pretending to be) but his accounts are also being deleted, either by YouTube AI classifying him as a spammer or by getting community strikes because somebody tricked him into going on a rant about Hitler. This is why most of the videos in this thread no longer exist. Perhaps an aspie out there should take it upon themselves to archive these videos somewhere. Within the Duffverse Circle of Account Chaos there is an endless stream of reuploaded commercials, future Walmart locations, re-releases of television shows with new elements, plans for new films featuring Joshua himself and so much more. I've done a bit of digging but who knows how many Joshua controlled accounts there are. Just searching the name of a brief reference he makes in a video could lead down a brand new rabbit hole.
Schizophrenia
Not sure if he has schizophrenia. He seems more so to be a peculiar tard. I can see why people would find some of the stuff he posts to be creepy, but he's honestly just a good hearted retarded guy. For example, his search for a "new papaw" is a reference to his dead grandfather Jim C. Bailey who was a very accomplished educator who I can only assume Joshua was very close to. I believe there's an old video of his where he's breaking down crying because his grandfather died, and ever since then he has been on the search for a new papaw, which is basically any older male who is nice to him. I find his content to be charmingly innocent actually. Anyway here's is an example from his Facebook of one of his new papaws.
Trolling
Obviously Joshua is incredibly easy to troll. This has essentially resulted in edgy teenagers getting him to say dumb stuff for their amusement like "Gas the jews", "I hate niggers" and other such boring and overdone tropes. I think it's much more interesting to just egg him on in his endeavors and encourage to get more involved in his own original epic causes like "punishing spongebob for being annoying", "promising not to massage his girl cousin's without asking permission ever again", or "putting toothless people in the electric chair". There's not a lot anyone can do to keep boring trolls from reaching out to Joshua, but I think it should be kept in mind that the gymnastics happening in his head are often much sweeter cow milkies and much more fascinating than him making 9/11 jokes or whatever.
Anyway, that's all for now. I'll be hanging around this thread. Feel free to share theories, discuss ect. He's truly one of the most entertaining people on YouTube.
Here's a fun Joshua maymay somebody sent me:
