Well said Stalin. You laid it out there and I've also been thinking along the same lines, though I didn't know of any actual incidents of auditory hallucinations. I have been thinking along the schizophrenia lines since I first started learning about Jace. However, one thing now makes me second guess this. The other day I asked in the general thread what, if anything, is known of of Jace's behavior prior to his rise to internet infamy. DeagleDad420 responded basically saying that someone claiming to have gone to high school with Jace posted on Jace's tumblr (I think) a few years ago basically saying that Jace has behaved this way for a while now. Later Tyce seemed to corroborate this. Now, as I recall (I'm not a psychiatric professional either) everything I've ever read and experienced about schizophrenia has indicated that symptoms begin to manifest in late teens (18, 19) at the earliest, generally more towards the early twenties. If Jace was already delusional since his early to mid teens, well it casts some doubt in my mind regarding schizophrenia. Now I'm sure there are exceptions and more to it all, I don't know, but that is my most recent line of thinking about it.
This is a common view to hold if you've only been following him for two or three months. But Jace was way, way less delusional and crazy when Fuck Yeah Deagles first started out. He even
admitted he was wrong a few times and, God forbid, actually
took advice from experts. Most of his delusions were about gun trivia; he didn't ever call himself Stryker, and referred to himself as only a "Future marine", never an actual Marine; nowadays, he's much, much more lenient to indulge in fantasy and nonsense comparatively speaking. During the Fuck Yeah Deagles era, he was basically just a stupid dudebro, not a schizophrenic.
For an example, watch this video (his first ever made, posted on Nov 7 2012) and compare it to his more recent adventures. The dudebro attitude definitely still shines through today, but there's a much greater level of delusion and mental illness.
Another thing of note: We're not quite sure yet if he is 20 or 22. On Tumblr he repeatedly said he was 19 (
http://parkourdude91.tumblr.com/post/34265704093/more-about-parkourdude) and during the "Final Vlog" video he said he was "going to be 20 soon", referencing his upcoming October birthday. Assuming he's currently 20 his birthdate would be '93... I can't recall him ever referencing his birthdate aside from his username "91" which would put him at 22. He's yet to come up with a convincing reason as to why he would have chosen those numbers aside from birthdate so it's kind of a toss-up as to whether he's 20 or 22. In the very first video WachtAmWeb made about him, he made a point saying how odd it was that someone older than him (Wacht was born in '92) could be so dumb, to which Jace's response was "it's just a fuckin' number dude". He said the same in the "trial" later on. It's also possible he just made up the number at the end of his username to posture online and sound older (and therefore somehow cooler) than he actually was.
This is all a very long way of saying we don't quite know his age exactly.
Why on earth does he honestly believe his toy guns are real weapons? Is it a symptom of whatever mental dysfunction he has or is it just hardcore wishful thinking?
For a while I didn't think he actually believed airsoft can literally kill people (I could be wrong) I thought he was just posturing in an attempt to intimidate others while inflating his own ego, the same kind of voluntary suspension of disbelief that allows one to get immersed in a game or a movie (after all, airsoft is basically just one big manly game of play pretend cops and robbers) But from the recent Civil War videos, the way he talks about "putting Brandon on ice" and shit... I really don't know anymore.
Do you know something I don't?
